B Pins 13 and 14 can be either directly connected to the ground or connected to the ground using a retractable device. The DisplayPort A Mini DisplayPort receptacle (centre) with Thunderbolt 3 port (left) and power input (right) DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is mainly used to connect the video source to a display device, such as a computer monitor, and it can also carry audio, USB and other forms of data. DisplayPort was designed to replace VGA, FPD-Link and digital visual interface (DVI). The back interface is compatible with others such as HDMI and DVI, using active or passive adapters. DisplayPort review is the first display interface to rely on packaged data, a form of digital digital in technologies such as Ethernet, USB and PCI Express. This allows the use of internal and external display connections, and unlike outdated standards that transmit an hour-long signal with each output, the DisplayPort protocol is based on small data packets known as micro-packs that can insert a clock signal into the data stream. This allows you to get a higher resolution using fewer contacts. Using data packets also makes DisplayPort possible to be exuding, which means that additional features can be added over time without significant changes to the physical interface. DisplayPort can be used to transmit audio and video at the same time, although each one is optional and can be streamed without the other. The path of the video signal can range from six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit, 192 kHz PCM audio that is not compressed. A two-direction, semi-duplex support channel carries device management and device management data for the main link, such as VESA EDID, MCCS, and DPMS standards. In addition, the interface is capable of carrying two-direction USB signals. DisplayPort uses an LVDS signal protocol that is not compatible with DVI or HDMI. However, dual-mode Ports DisplayPort are designed to transmit the DVI or HDMI protocol with a single link (TMDS) through the interface using an external passive adapter. This adapter provides compatibility mode and converts the signal from 3.3 volts to 5 volts. Analog VGA/YPbPr and two-edge DVI require an active powered adapter for compatibility and does not rely on dual mode. Active VGA adapters are powered directly by the DisplayPort connector, while active dual-link DVI adapters typically rely on an external power source such as USB. Versions 1.0 to 1.1 The first version, 1.0, was approved by VESA on May 3, 2006. Version 1.1 was ratified on April 2, 2007, and version 1.1a was ratified on January 11, 2008. DisplayPort 1.0-1.1a allows a maximum bandwidth of 10.8 Gbit/s (8.64 Gbit/s data speed) over the standard 4-band main link. DisplayPort cables up to 2 metres long are required to maintain a full capacity of 10.8 Gbps. DisplayPort 1.1 allows devices to implement alternative layers of communication, such as fiber optic, allowing for much longer reach between the source and the display without signal degradation, although alternative implementations are not standardized. It also includes HDCP in addition to DisplayPort Content Protection (DPCP). DisplayPort 1.1a is free to download from the VESA website. Version 1.2 DisplayPort 1.2 was introduced on January 7, 2010. The most significant improvement in the new version is the doubling of bandwidth up to 17.28 Gbps in High Bit Rate 2 (HBR2) mode, allowing you to increase resolution, higher upgrade speeds and greater color depth. Other improvements include yourself independent video streams (multi-stream transport) called Multi-Stream Transport, stereoscopic 3D tools, AUX bandwidth increase (from 1 Mbps to 720 Mbps), more color spaces including xvYCC, scRGB and Adobe RGB 1998, and Global Time Code (GTC) to synchronize audio/video. In addition, Apple Inc.'s Mini DisplayPort connector, which is much smaller and is designed for laptops and other smaller devices, is compatible with the new standard. Version 1.2a DisplayPort 1.2a was released in January 2013 and may additionally include adaptive VESA synchronization. AmD FreeSync uses DisplayPort Adaptive-Sync to work. FreeSync was first demonstrated at CES 2014 on the Toshiba Satellite laptop, using the Panel-Self-Refresh (PSR) feature from Embedded DisplayPort, and after an offer from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an additional feature of the main DisplayPort standard called Adaptive-Sync Because it is a non-binding feature, Adaptive-Sync support is not required for display to be DisplayPort 1.2a compatible. 1.3 Version 1.3 DisplayPort was approved on September 15, 2014. This standard increases the total transmission capacity to 32.4 Gbps with the new HBR3 mode from 8.1 Gbps per lane (according to 5.4 Gbps HBR2 in version 1.2), for total data bandwidth of 25.92 Gbit/s after factoring in 8b/10b encoding overheads. This bandwidth is enough for a 4K UHD display (3840 × 2160) at 120 Hz with 24 bits / px RGB colors, 5K display (5120 × 2880) at 60 Hz with 30 bits / px RGB color, or 8K UHD display (7680 × 4320) at 30Hz with 24 bits / px RGB color. Using Multi-Stream Transport (MST), DisplayPort can control two 4K UHD (3840 × 2160) displays at 60 Hz or up to four W'HXGA displays (2560 × 1600) at 60 Hz with a 24-bit/px RGB color. The new standard includes mandatory dual mode for DVI and HDMI adapters, introduction of HDMI 2.0 and HDCP 2.2 content protection. The Thunderbolt 3 connection standard was originally supposed to include DisplayPort 1.3, but the final release ended with only version 1.2. VeSA adaptive synchronization in 1.3 DisplayPort remains an additional part of the specification. Version 1.4 displayPort was published on March 1, 2016. The new transmission modes are not defined, so HBR3 (32.4 Gbit/s) presented in version 1.3 is still the most affordable mode. DisplayPort 1.4 adds support for compression display flow 1.2 (DSC), Correction errors forward, HDR10 metadata defined in CTA-861.3, including static and dynamic metadata and Rec color space. 2020, for HDMI compatibility, and maximum number of stationary audio channels of audio channels DSC is a visually no loss method of coding with a compression ratio of up to 3:1. Using HBR3 DSC, DisplayPort 1.4 can support 8K UHD (7680 × 4320) at 60Hz or 4K UHD (3840 × 2160) at 120 Hz with 30 bit/px RGB and HDR. 4K by 60 Hz 30 bits / px RGB/ HDR can be achieved without the need for DSC. On displays that do not support DSC, maximum limits remain unchanged from DisplayPort 1.3 (4K 120 Hz, 5K 60 Hz, 8K 30Hz). Version 1.4a DisplayPort 1.4a was published in April 2018. VESA has not made an official press release for this version. It updated the DSC DisplayPort implementation from DSC 1.2 to 1.2a. According to a roadmap published by VESA in September 2016, the new version of DisplayPort was to be launched in early 2017. This would improve the communication speed from 8.1 to 10.0 Gbps, which is 24% more. However, no new version released in 2017 is likely to be delayed to make further improvements after the HDMI Forum announced in January 2017 that their next standard (HDMI 2.1) would offer up to 48 Gbit/s bandwidth. According to a press release dated January 3, 2018, VESA is also currently involved with its members in the development of the next standard generation of DisplayPort, with plans to increase the data speed enabled by DisplayPort twice and beyond. VESA plans to publish this update within the next 18 months. At CES 2019, VESA announced that the new version will support 8K and 60 Hz without compression and is expected to be released in the first half of 2019. On June 26, 2019, VESA officially released DisplayPort 2.0. VESA stated that DP 2.0 is the first major update to DisplayPort since March 2016 and provides up to ≈3× improved data speed (from 25.92 to 77.37 Gbps) compared to the previous version of DisplayPort (1.4a), as well as new opportunities to meet future performance requirements for traditional displays. These include more 8K resolutions, higher upgrade rates and higher dynamic range (HDR) support at higher resolutions, improved support for multiple display configurations, and improved user experience with augmented/virtual reality (AR/VR) displays, including support for 4K-and-over VR resolution. Products including DP 2.0 are projected to be non-market until the end of 2020. Examples of DP 2.0 configuration with increased bandwidth enabled by DP 2.0, VESA offers a high degree of versatility and configurations for higher display permissions and upgrade speeds. In addition to the aforementioned 8K resolution on 60 Hz with HDR support, DP 2.0 via native DP or via USB-C as DisplayPort Alt Mode allows various high performance configurations: One display display Один дисплей 16K (15360 × 8640) 60 Гц с 10 bpc (30 бит/px, HDR) RGB/Y'CBCR 4:4:4 цвет (с DSC) Один 10K (10240 × 4320) дисплей 60 Гц и 8 bpc (24 бит/px, SDR) RGB/Y'CBCR 4:4:4 цвет (несыхепаемый) Двойное разрешение дисплея Два 8K (7680 × 4320) отображает 120 Гц и 10 bpc (30 бит/px, HDR) RGB/Y'CBCR 4:4:4 цвет (с DSC) Два 4K (3840 × 2160) отображает 144 Гц и 8 bpc (24 бит/px, SDR) RGB/Y'CBCR 4:4:4 цвет (несыщенный) Тройной дисплей резолюций Три 10K (10K0240 × 4320) отображает 60 Гц и 10 bpc (30 бит/px, HDR) RGB/Y'CBCR 4:4:4 цвета (с DSC) Три 4K (3840 × 2160) отображает 90 Гц и 10 bpc (30 бит/px) , HDR) RGB/Y′CBCR 4:4:4 color (uncompressed) When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video , DP 2.0 can enable such configurations as:[32] Three 4K (3840 × 2160) displays @ 144 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′CBCR 4:4:4 color (with DSC) Two 4K × 4K (4096 × 4096) displays (for AR/VR headsets) @ 120 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′CBCR 4:4:4 color (with DSC) Three QHD (2560 × 1440) @ 120 Hz and 8 bpc (24 bit/px, SDR) RGB/Y′CBCR 4:4:4 color (uncompressed) One 8K (7680 × 4320) display @ 30 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′CBCR 4:4:4 color (uncompressed) Specifications Main specifications DisplayPort version 1.0–1.1a 1.2–1.2a 1.3 1.4–1.4a 2.0 Release date May 2006 (1.0)[33]Mar 2007 (1.1)[34]Jan 2008 (1.1a)[8] Jan 2010 (1.2)[11]May 2012 (1.2a)[34] Sep 2014[ 19] March 2016 (1.4)[22]April 2018 (1.4a)[26] June 2019[32] Main link Transmission modes : RBR (1.62 Gbit/s per lane) Yes[35](§1.6.1) Yes Yes Yes Yes HBR (2.70 Gbit/s per lane) Yes[35](§1.6.1) Yes Yes Yes Yes HBR2 (5.40 Gbit/s per lane) No Yes[36](§2.1.1) Yes Yes Yes HBR3 (8.10 Gbit/s per lane) No No Yes[19] Yes Yes UHBR 10 (10.0 Gbit/s per lane) No No No No Yes UHBR 13.5 (13.5 Gbit/s per lane) No No No No Yes UHBR 20 (20.0 Gbit/s per lane) No No No No Yes Number of lanes (§1.7.1)[8] 4 4 4 4 4 Maximum total bandwidth[a] 10.80 Gbit/s 21.60 Gbit/s 32.40 Gbit/s 32.40 Gbit/s 80.00 Gbit/s Maximum total data rate[b] 8.64 Gbit/s 17.28 Gbit/s 25.92 Gbit/s 25.92 Gbit/s 77.37 Gbit/s Encoding scheme[c] (§1.7.1)[8] 8b/10b 8b/ 10b 8b/10b 8b/10b 128b/132b Сжатие (необязательно) - - DSC 1.2 (DP 1.4)DSC 1.2a (DP 1.4a) DSC 1.2a Вспомогательный канал Максимальная пропускная способность (рис. 3-3) 2 Мбит/с (3,4) 720 Мбит/с 720 Мбит/с 720 Мбит/с 720 Мбит/с?

Some of the transmitted bits are used for coding purposes, so the speed of video transmission through the DisplayPort interface is only a fraction of the total bandwidth. so that only 80% of bandwidth is available for data bandwidth. An additional 2 bits are used to balance DC (providing roughly equal amounts of 1s and 0s). They consume bandwidth but do not provide any data. In DisplayPort 1.0-1.1a, RGB images are simply sent without any specific color content information As The Main Link DisplayPort main link is used to transmit video and audio. The main link consists of a number of unidirectional serial data channels that work simultaneously, called lanes. The standard DisplayPort connection has four lanes, although some DisplayPort applications implement more, such as the Thunderbolt 3 interface, which sells up to 8 DisplayPort lanes. In the standard DisplayPort connection, each band has a special set of twisted pair wires and transmits data through it using a differential alarm. It's a self-affirming system, so you don't need a dedicated hour-long signal channel. Unlike DVI and HDMI, which change the transmission speed to the exact speed required for a particular video format, DisplayPort only works on Specific speeds; Any extra bits in the gear are filled with stuffing of characters. (2,2,1.4 euros) In DisplayPort 1.0-1.4a data data encoded by ANSI 8b/10b coding before transmission. In this scheme, only 8 out of every 10 bits transferred are data; additional bits are used to balance DC (providing roughly equal amounts of 1s and 0s). As a result, the data rate is only 80% of the physical bitrate. The transmission speed is also sometimes expressed from the Point of View of Link Symbol Rate, which is the speed at which these 8b/10b characters are encoded (i.e. the speed at which groups of 10 bits are transmitted, 8 of which represent data). The following modes of transmission are defined in version 1.0-1.4a: RBR (Lower bit speed): 1.62 Gbit/s bandwidth per lane (162 MHz link symbol speed) HBR (High bit speed): 2.70 Gbit/s bandwidth per lane (270 MHz link speed) H2BR (High speed bit 2): 5 .5.0 40 Gbit/s bandwidth per lane (540 MHz link symbol speed) entered in DP 1.2 HBR3 (High bit speed 3): 8.10 Gbit/s bandwidth per lane (810 MHz link speed symbol) introduced in DP 1.3 DisplayPort 2.0 uses 128b/132b coding; each group of 132 bits transmitted represents 128 bits of data. The effectiveness of this scheme is 96.96%. In addition, Forward Error Correction (FEC) consumes a small amount of connection bandwidth, resulting in an overall efficiency of ≈96.7%. The following modes of transmission are added to DP 2.0: UHBR 10 (Ultra High Bit Rate 10): 10.0 Gbit/s bandwidth on the UHBR 13.5 strip (Ultra High Bit Rate 13.5): 13.5 Gbit/s bandwidth per UHBR 10 20 (Ultra High Bit Rate 20): 20.0 Gbit/s bandwidth per main bandwidth in a standard 4-lane connection is a total of all lanes: RBR: 04 × 1.62 Gbit/s 06.48 Gbit/s pass HBR: 04 × 2.70 Gbit/s or 648 MB/s with coding 8b/10b) HBR: 04 × 2.70 Gbit/s 10.80 Gbit/s bandwidth (data speed 8.6 4 Gbit/s or 1.08 GB/s) HBR2: 4 × 5.40 Gbit/s and 21.60 Gbit/s bandwidth (data speed 17.28 Gbit/s or 2.16 GB/s) HBR3 : 4 × 8,10 Гбит/с и 32,40 Гбит/с пропускная способность (скорость передачи данных 25,92 Гбит/с или 3,24 ГБ/с) UHBR 10: 4 × 10,0 Gbit/s 40.00 Gbit/s пропускная способность (скорость передачи данных 38.69 Gbit/s или 4.84 GB/s с кодированием 128b/132b и FEC) UHBR 13.5: 4 × 13,5 Гбит/с и 54,00 Гбит/с пропускная способность (скорость передачи данных 52,22 Гбит/с или 6,52 ГБ/с) UHBR 20: 4 × 20,0 Гбит/с 80.00 Gbit/s пропускная способность (скорость передачи данных 77.37 Gbit/s или 9.69 GB/s) Режим передачи, используемый основной ссылкой DisplayPort, обсуждается источником и устройством раковины, когда соединение сделано, через процесс под названием Link Training. This process The highest possible connection speed. If the quality of the DisplayPort cable is not sufficient to handle HBR2 speeds reliably, for example, DisplayPort devices will review this and switch to a lower mode to maintain a stable connection. The link can be re-agreed at any time if the synchronization loss is lost Audio data is transmitted to the main link during video processing intervals (short pauses between each line and the video frame). The DisplayPort AUX Auxiliary Channel is a semi-duplex bidirectional data channel used for a variety of additional data, in addition to video and audio (such as I2C or CEC commands) ( ...... AUX signals are transmitted through a special set of twisted pairs of wires. DisplayPort 1.0 has identified Manchester coding at 2 Mbaud signal speed (1 Mbit/s data speed). (No.3.4) DisplayPort 1.2 introduced a second transmission mode called FAUX (Fast AUX), which runs on the 720 Mbaud with 8b/10b (576 Mbit/s data speed). This can be used to implement additional transport protocols such as USB 2.0 (480 Mbit/s) without the need for an additional cable, but has seen little practical use as of 2018. Cables and Cable Connectors Compatibility and Support function All DisplayPort cables are compatible with all DisplayPort devices, regardless of the version of each device or the level of cable certification. All DisplayPort features will be able to function in any DisplayPort cable. DisplayPort does not have multiple cable designs; all DP cables have the same basic layout and wiring, and will support any function, including audio, chamomile chain, G-Sync/FreeSync, HDR and DSC. DisplayPort cables are supportive of transmission speed. DisplayPort identifies four different transmission modes (RBR, HBR, HBR2 and HBR3) that support gradually higher bandwidth. Not all DisplayPort cables are capable of all four modes of transmission. VESA offers certificates for each bandwidth level. These certificates are optional, and not all DisplayPort cables are VESA certified. Limited transmission cables are still compatible with all DisplayPort devices, but may limit the maximum resolution or speed of upgrade. DisplayPort cables are not classified according to the version. Although cables are usually labeled with version numbers, HBR2 cables are advertised as DisplayPort 1.2 cables, for example, this notation is not allowed by VESA. Using cable version numbers may mean that displayPort 1.4 requires DisplayPort 1.4 or that features presented in DP 1.4, such as HDR or DSC, will not function with older DP 1.2 cables when none of them actually matter. DisplayPort cables are classified only by level bandwidth (RBR, HBR, HBR2, HBR3) if they have been certified at all. Cable bandwidth and certificates Not all DisplayPort cables are capable of operating at the highest level of bandwidth. Cables can be submitted to VESA for additional certification at different bandwidth levels. VESA offers three levels of cable certification: RBR, Standard and DP8K. These Are These DisplayPort кабели для надлежащей работы на следующих скоростях: DisplayPort Кабельные сертификаты Передачи Режим ПередачиBit Скорость DP ВерсияИнтрондировано в минимальной кабельной сертификации Требуется RBR (Снижение скорости бита) 6.48 Gbit/s 1.0 RBR DisplayPort Кабель HBR (Высокая скорость бита) 10.80 Gbit/s Стандартный DisplayPort Кабель HBR2 (Высокая скорость бита 2) 21.60 Gbit/s Стандартный DisplayPort Кабель HBR2 1.2 HBR3 (Высокая битовая ставка 3) 32.40 Gbit/s 1.3 DP8K DisplayPort Cable UHBR 10 (Ultra High Bit Rate 10) 40.00 Gbit/s 2.0 В апреле 2013 года VESA опубликовала статью о том, что сертификация кабеля DisplayPort не имеет четких уровней пропускной способности HBR и HBR2, и что любой сертифицированный стандартный кабель DisplayPort, в том числе сертифицированный в соответствии с DisplayPort 1.1, сможет обрабатывать пропускную способность 21,6 Гбит/с HBR2 that was introduced with the DisplayPort 1.2 standard. DisplayPort 1.2 defines only one specification for High Bit Rate cable builds, which is used for both HBR speeds and HBR2, although the DP cable certification process is governed by displayPort PHY (CTS) compliance check standard, not DisplayPort standard. (36 euros, 4.1 euros) THE DP8K certification was announced by VESA in January 2018 and certifies the cables for proper operation at HBR3 speeds (8.1 Gbps per strip, 32.4 Gbps). In June 2019, with the release of DisplayPort's 2.0 version 2.0, VESA announced that DP8K certification was also sufficient for the new UHBR 10 transmission mode. No new certificates for UHBR 13.5 and UHBR 20 modes have been announced. VESA encourages displays to use tethered cables for these speeds rather than releasing standalone cables to the market. It should also be noted that the use of display flow compression (DSC) introduced in DisplayPort 1.4 significantly reduces cable bandwidth requirements. Formats that are typically outside DisplayPort 1.4, such as 4K (3840 × 2160) at 144 Hz 8 bpc RGB/4:4:4 (31.4 Gbps) can only be implemented with DSC. This will reduce the physical bandwidth requirements by 2-3x by placing it within the capabilities of the HBR2-rated cable. This illustrates why DisplayPort cables are not classified by version; although the DSC was introduced in version 1.4, that doesn't mean it needs the so-called DP 1.4 cable (HBR3-rated cable) to work. HBR3 cables are only needed for applications that exceed HBR2 bandwidth, not just for any DisplayPort 1.4 application. If DSC is used to reduce bandwidth requirements to HBR2, HBR2-rated cables will suffice. DisplayPort standard cable length does not specify the maximum length of cables, although DisplayPort 1.2 sets a minimum requirement for all cables up to 2 metres long must maintain HBR2 HBR2 speed and all cables of any length must support RBR speed (6.48 Gbit/s). (5.7.1 euros, 4.1 euros) Cables more than 2 meters long may or may not support HBR/HBR2 speed, and cables of any length may or may not support HBR3 speed. The connectors and configuration of the DisplayPort pin output on the DisplayPort computer cables and ports can have either a full-size connector or a mini connector. These connectors are only physically fit - DisplayPort features the same no matter what connector is used. Using the Mini DisplayPort connector does not affect the performance or support of the connection. The full-size DisplayPort Connector Standard DisplayPort connector (now referred to as a full-size connector that distinguishes it from the mini connector) is the only type of connector introduced in DisplayPort 1.0. It is a 20-pin single-target connector with a friction lock and an extra mechanical latch. The standard DisplayPort vessel has dimensions of 16.10 mm (width) × 4.76 mm (height) × 8.88 mm (deep). The Standard distribution of DisplayPort connector pins is as follows: 8 (4.2.1) 12 pins for the main link - the main link consists of four protected twisted pairs. Each pair requires 3 pins; one for each of the two wires and the third for the shield. (No.4.1.2, p183) (contacts 1-12) 3 pins for the auxiliary channel - the auxiliary channel uses another three-pin screened twisted pair (contacts 15-17) 1 pin for HPD - hot plug Detecting pin (contact 18) 2 pins for power - 3.3 V power and backline (contacts 19 and 20) 2 additional ground pins - (contacts 13 and 14) Mini DisplayPort connector Mini DisplayPort connector was developed by Apple for use in its computer products. It was first announced in October 2008 for use in the new MacBook Pro, MacBook Air and Cinema Cinema Display. In 2009, VESA adopted it as the official standard, and in 2010 the specification was combined into the main DisplayPort standard with DisplayPort 1.2. Apple freely licenses the veSA specification. The Mini DisplayPort (mDP) connector is a 20-pin single- orientation connector with friction lock. Unlike the full-size connector, it does not have the capacity for a mechanical latch. The MDP vessel is 7.50 mm (wide) × 4.60 mm (height) × 4.99 mm (deep). The mDP pin appointments are the same as the full-size DisplayPort connector. The DP_PWR Pin Pin 20 on a DisplayPort connector called DP_PWR, 3.3 V (±10%) DC power up to 500 mA (minimum capacity of 1.5 W). This power is available from all DisplayPort vessels, both on the original and on displays. DP_PWR is designed to power adapters, reinforced cables similar devices, so a separate power cable is not necessary. Standard DisplayPort DisplayPort cable Do not use DP_PWR pin. Connecting DP_PWR the contacts of the two devices directly together through a cable can create a short circuit that could potentially damage the devices, since DP_PWR pins on two devices are unlikely to have exactly the same voltage (especially with ±10% tolerance). For this reason, DisplayPort 1.1 and later standards indicate that DisplayPort-to-DisplayPort passive cables must leave the pin code 20 unconnected. However, in 2013, VESA announced that after investigating reports of faulty DisplayPort devices, it found that a large number of unruly vendors were making their DisplayPort cables with a plugged DP_PWR: VeSA had recently experienced quite a few complaints about the troublesome operation of DisplayPort, which was eventually caused by the wrong Display Cables. These bad DisplayPort cables are usually limited to non-DisplayPort certified cables, or off-brand cables. To further explore this trend in the DisplayPort cable market, VESA acquired a number of non-certified off-label cables and found that an alarmingly large number of them had been configured incorrectly and probably would not support all system configurations. None of these cables would pass the DisplayPort certification test, moreover, some of these cables could potentially damage your computer, laptop, or monitor. The provision DP_PWR wires not to miss out on standard DisplayPort cables was not in the DisplayPort 1.0 standard. However, DisplayPort products (and cables) didn't start to appear on the market until 2008, long after version 1.0 was replaced by version 1.1. DisplayPort 1.0 has never been implemented in commercial products. The resolution and frequency of the update limits the tables below to describe the frequency of updates that can be achieved with each mode of transmission. In general, the maximum upgrade frequency is determined by transmission mode (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, or UHBR 20). These transmission modes were introduced to the DisplayPort standard as follows: RBR and HBR were defined in the initial release of the DisplayPort standard, Version 1.0 HBR2 was introduced in version 1.2 HBR3 was presented in version 1.3 UHBR 10, UHBR 13.5, and UHBRBR 20 was presented in version 2.0 However, transmission support was not necessarily dictated by the stated display number. For example, older versions of displayPort Marketing Guidelines have allowed a device to be labeled as DisplayPort 1.2 if it supported the MST function, even if it did not support the HBR2 transmission mode. (p9) The new versions of the guidelines have removed this provision, and there are currently no guidelines for the DisplayPort in products. Thus, DisplayPort version numbers are not reliable reliable о том, какие скорости передачи устройство может поддерживать. Кроме того, отдельные устройства могут иметь свои собственные произвольные ограничения сверх скорости передачи. Например, графические процессоры NVIDIA Kepler GK104 (такие как GeForce GTX 680 и 770) поддерживают DisplayPort 1.2 в режиме передачи HBR2, но ограничены 540 Мп/с, что составляет всего 3⁄,4 от максимально возможного с HBR2. Следовательно, некоторые устройства могут иметь ограничения, которые отличаются от тех, которые перечислены в следующих таблицах. Для поддержки определенного формата устройства источника и дисплея должны поддерживать необходимый режим передачи, а кабель DisplayPort также должен быть способен обрабатывать необходимую пропускную способность этого режима передачи. (См.: Кабели и разъемы) Для всех форматов в этих таблицах предполагается обновить ограничения частоты для стандартной глубины цвета видео 8 bpc (24 бит/px или 16,7 млн цветов). Это стандартная глубина цвета, используемая на большинстве компьютерных дисплеев. Обратите внимание, что некоторые операционные системы относятся к этому как 32-битная глубина цвета - это то же самое, что 24-битная цветовая глубина. 8 дополнительных битов для альфа-канала информации, которая присутствует только в программном обеспечении. На этапе передачи эта информация уже включена в первичные цветные каналы, поэтому фактические видео данные, передаваемые по кабелю, содержат только 24 бита на пиксель.

DisplayPort 1.0-1.4a uses 8b/10b coding, which means that 80% of the bits sent over the link represent data, while the remaining 20% is used for coding purposes. Maximum bandwidth rbR, HBR, HBR2 and HBR3 (6.48, 10.8, 21.6 and 32.4 Gbps), thus transporting video data at rates of 5,184, 8.64, 17.28 and 25.92 Gbps. DisplayPort version 2.0 uses coding 128b/132b, and therefore maximum bandwidth UHBR 10, 13.5, and 20 (40, 54 and 80 Gbit/s) transport data at rates 39.69, 52.22 and 77.37 Gbps. The non-repressive data rate for RGB video in bits per second is calculated as bits per pixel × pixels per frame × frames per second. Pixels per frame include CVT-R2-defined blank intervals. This format can only be achieved with the full RGB color if DSC (display flow compression) is used. This format can only be achieved if the YCBCR format is used with 4:2:2 or 4:2:0 chroma subsampling (as noted) - This format can only be achieved if the DSC is used together with YCbCr 4:2:2 or 4:2:0 chroma subs For all formats in these tables, assumed that for all formats in these tables, this format assumes that this format is slightly higher than the maximum data transfer rate of this transmission mode with CVT-R2, it is close enough to be achieved with non-standard Update frequency limitations for HDR-video-color depth of 10 bpc (30 bits/px or 1.07 billion colors). This depth of color is a requirement for various common HDR standards such as HDR10. This requires 25% more bandwidth than the standard 8 Bpc video. HDR extensions have been identified in version 1.4 of the DisplayPort standard. displays support these HDR extensions, but can only implement HBR2 mode if no additional HBR3 bandwidth is needed (e.g. on 60 Гц HDR дисплеев). Поскольку нет определения того, что представляет собой DisplayPort 1.4 устройство, некоторые производители могут выбрать для обозначения их как DP 1.2 устройств, несмотря на их поддержку DP 1.4 HDR расширений. В результате DisplayPort «номера версий» не должны использоваться в качестве индикатора поддержки HDR.

Dual mode is an additional feature, so not all DisplayPort sources necessarily support passive DVI/HDMI adapters, although in practice almost all devices do so. Officially, the DPP logo should be used to refer to the DP port, which supports dual mode, but most modern devices do not use the logo. Devices that implement dual mode detect that a DVI or HDMI adapter is attached and send DVI/HDMI TMDS signals instead of DisplayPort signals. The original DisplayPort Dual-Mode standard (version 1.0) used in DisplayPort 1.1 devices only supported TMDS clock speeds of up to 165 MHz (4.95 Gbps). This is equivalent to HDMI 1.2, and enough for up to 1920 × 1200 by 60 Hz. In 2013, VESA released a dual-Mode 1.1 standard that added support to 300 MHz TMDS watches (9.00 Gbps) and is used in new DisplayPort 1.2 devices. That's a little less than the 340 MHz maximum HDMI 1.4, and enough for up to 1920 × 1080 by 120 Hz, 2560 × 1440 at 60Hz, or 3840 × 2160 at 30 Hz. The old adapters, which were only capable at a speed of 165 MHz, were retroactively named Type 1 adapters, with new 300 MHz adapters called Type 2. With the release of the DisplayPort 1.3 standard, VESA has added dual support to the 600 MHz TMDS watch (18.00 Gbit/s bandwidth), full HDMI 2.0 bandwidth. This is enough for the 1920 × 1080 by 240 Hz, 2560 × 1440 at 144 Hz, or 3840 × 2160 by 60 Hz. However, by 2018, no passive adapter capable of 600 MHz dual mode was produced. Double DisplayPort restriction mode for DVI adapter after removing its case. The chip on the board converts the voltage levels generated by a dual-mode DisplayPort device to be compatible with the DVI monitor. Limited adapter speed - Although pinout and digital signal values transmitted by the DP port are identical to the native source of DVI/HDMI, the signals are transmitted at native voltage DisplayPort (3.3 V) instead of the 5 V used by DVI and HDMI. As a result, two-circuit adapters must contain a level shift scheme that changes voltage. Having this chain limits the speed of the adapter, so every higher speed added to the standard requires new adapters. Unidirectional - Although the dual mode standard defines a method for DisplayPort sources for displaying DVI/HDMI signals using simple passive adapters, there is no analogue standard to give DisplayPort displays the ability to receive DVI/HDMI signals through passive adapters. As a result, DisplayPort displays can only receive DisplayPort signals in their native language; any DVI or HDMI signals must be converted to DisplayPort format with active device DVI и HDMI HDMI can't be connected to DisplayPort displays with passive adapters. Single DVI Only - Since displayPort dual mode works using DisplayPort connector contacts to send DVI/HDMI signals, the 20-pin DisplayPort connector can only produce a single-message DVI signal (which uses 19 contacts). The dual DVI signal uses 25 pins, so it is therefore impossible to transfer the native from the DisplayPort connector through a passive adapter. DVI dual-bond DVI signals can only be obtained by converting from native DisplayPort output signals to an active conversion device. Unavailable on USB-C - The DisplayPort alternative mode specification for sending DisplayPort signals via USB-C cable does not include support for the dual-mode protocol. As a result, passive DP-to-DVI and DP- to-HDMI adapters do not function in a chain from USB-C to DP adapter. Multi-Stream Transport (MST) Multi-Stream Transport is a feature first introduced in DisplayPort 1.2. This allows you to control multiple independent displays from a single DP port on the original devices by multiplexing multiple video streams into one stream and sending it to a device branch that demultiplexes the signal into the original streams. Branch devices are usually found in the form of an MST hub that connects to a single DP input port and provides multiple outlets, but it can also be implemented on display internally to provide a DP exit port for the chamomile chain by effectively embedding a 2-port MST hub inside the display. (Figure 2-59) Can theoretically be supported by up to 63 displays, but the cumulative data speed requirements for all displays may not exceed the limits of a single DP port (17.28 Gbps for DP 1.2, or 25.92 Gbit/s for DP port 1.3/1.4). In addition, the maximum number of connections between the source and any device (i.e. the maximum length of the daisy chain) is 7.36 (2.5.2), and the maximum number of physical output ports on each branch device (e.g. hub) is 7. With the release of MST, the standard single-seat operation was retroactively called the Single-Stream Transport mode. The Daisy Chain is a feature that must be specifically supported by each intermediate display; not all DisplayPort 1.2 devices support it. The Daisy Chain requires a special DisplayPort output port on display. The standard DisplayPort input ports found on most displays cannot be used as a output part of the daisy chain. Only the latest display in the daisy chain doesn't need specific feature support or a DP port exit. The DisplayPort 1.1 display can also be connected to MST hubs and can be part of the DisplayPort daisy chain if it is the last display in the chain. (2.5.1 euros) Ensuring the host system also needs to maintain MST for hubs or daisy chains to operate. While Microsoft Windows environments have full support for it, Apple is running currently do not support the MST or DisplayPort daisy chain hubs on macOS 10.15 (Catalina). DisplayPort-to-DVI and DisplayPort-to-HDMI adapters/cables may or may not function from the MST outlet port; support for this depends on the device. (quote needed) MST is supported by the USB Type-C DisplayPort alternative mode, so standard DisplayPort chains and MST hubs operate from Type-C sources with a simple Type-C adapter to DisplayPort. High Dynamic Range (HDR) main article: Highly dynamic VIDEO support for HDR video was presented in DisplayPort 1.4. It implements the CTA 861.3 standard for transporting static HDR metadata to EDID. DisplayPort 1.0 content protection includes an additional DPCP (DisplayPort Content Protection) from Philips that uses 128-bit AES encryption. It also has complete authentication and session keys creation. Each encryption session is independent and has an independent recall system. This part of the standard is licensed separately. It also adds the ability to test the proximity of the receiver and transmitter, a method designed to ensure users don't bypass the content protection system to send data from remote, non-automatic users. (No.6) DisplayPort 1.1 has added an optional implementation of the 56-bit HDCP (High-bandwidth Digital Content Protection) revision 1.3, which requires separate licensing from Digital Content Protection LLC. DisplayPort 1.3 added HDCP 2.2 support, which is also used by HDMI 2.0. The cost of VESA, the creators of the DisplayPort standard, thrusts that the standard is not for the royal family to be implemented. However, in March 2015, MPEG LA issued a press release stating that the $0.20 royalty rate per unit applied to DisplayPort products produced or sold in countries subject to one or more patents in the MPEG LA license pool, which includes patents from Hitachi Maxell, Philips, Lattice, Rambus and Sony. In response, VESA updated its displayPort frequently asked questions page with the following statement: MPEG LA states that DisplayPort requires a license and royalty payment. It is important to note that these are only CLAIMS. Whether these CLAIMS are relevant is likely to be decided in a U.S. court. As of August 2019, the official VESA frequently asked questions no longer mentions MPEG LA fees. While VESA does not charge any royalty fees for the device, VESA requires membership to access these standards. The minimum cost is currently $5,000 (or $10,000 depending on annual corporate sales revenue) per year. Benefits over DVI, VGA and FPD-Link This article built-in lists that may be poorly defined, unverified, or indiscriminate. Please help clean it up to meet Wikipedia quality standards. If necessary, include the elements in the main main Article. (November 2010) In December 2010, several computer vendors and display manufacturers, including Intel, AMD, Dell, Lenovo, Samsung and LG announced that they would begin phasing out FPD-Link, VGA and DVI-I over the next few years, replacing them with DisplayPort and HDMI. One notable exception to the list of manufacturers is Nvidia, which has not yet announced any plans for the future implementation of outdated interfaces. (quote needed) DisplayPort has a number of advantages over VGA, DVI and FPD-Link. The standard is available to all VESA members (questionable - discuss) with a mitigating standard to help broad adoption of 62 Smaller bands with built-in clocks, reduced EMI with data scrambling mode and spectrum distribution Based on micro-package protocol allows you to easily expand the standard with multiple types of data Flexible distribution of available bandwidth between audio and video Multiple video streams through one physical connection (version 1.2) Long distance through alternative physical media such as optical fiber (version 1.1a) high-resolution displays and multiple displays with a single connection, through hub or chamomile circuit hBR2 mode with 17.28 Gbit/s effective video bandwidth allows four simultaneous 108 0p60 displays (CEA-861 timings), two 2560 × 1600 × 30 bit 120 Hz (CVT-R timings), or 4K UHD (60 Hz) hBR3 mode with 25.92 Gbps/s efficient video bandwidth using CVT-R2 timings, allows eight simultaneous 1080p displays (1920 × 1080) 60 Hz, stereoscopic 4K UHD (3840 × 2160) 120 Hz, or 5120 × 2880 and 60 Hz each using 24 bits of RGB, or 5120 × 2880 and 60Hz each using 24 bits of RGB, and up to 8K UHD (7680 × 4320) - 60Hz using recharge 4:2:0, designed to work for internal communication from chip to chip, aimed at replacing internal FPD-Link links to displaying panels with a single communication interface compatible with the low-voltage signaling used with the submirin CMOS can control the displays directly, Eliminating scaling and scaling the circuit and allowing cheaper and thinner displays Link training with adjustable amplitude and pretivity adapts to different cable lengths and signal quality Reducing bandwidth for a 15-meter (49-foot) cable At least 1920 × 1080p and 60 Hz by 24 bits per pixel Full bandwidth transmission over 3 meters (9.8 ft) High-speed support channel for DDC, EDID, MCCS, DPMS, HDCP, adapter identification, etc. traffic can be used to transmit two-directional USB, touch data panels, CEC, and etc. Self-latching connector Comparison with HDMI Although DisplayPort has most of the same functionality as HDMI, it is an additional connection, in different scenarios. The displayPort double-pull port can emit an HDMI signal through a passive adapter. In 2008, HDMI Licensing, LLC charged an annual fee of $10,000 per large volume manufacturer and $0.04 to $0.15 per unit. (needs to be updated) Licensing, LLC objected to the free claim, stating that the DisplayPort specification states that companies can charge royalties for the implementation of DisplayPort. DisplayPort 1.2 has a larger bandwidth of 21.6 Gbps (17.28 Gbps with remote overheads), as opposed to HDMI 2.0's 18 Gbit/s (14.4 Gbit/s with remote overheads). DisplayPort 1.3 raises this level to 32.4 Gbps (25.92 Gbps with remote overheads), and HDMI 2.1 raises this level to 48 Gbit/s (42.67 Gbps with remote overheads), adding an additional TMDS link instead of an hour-long track. DisplayPort also has the ability to share this bandwidth with multiple audio and video streams for individual devices. The Port display has historically had a higher bandwidth than the HDMI standard available at the same time. The only exception is HDMI 2.1 (2017), which has a higher transmission bandwidth of 48 Gbit/s than DisplayPort 1.3 (2014) 32.4 Gbps. DisplayPort 2.0 (2019) overtook the transmission bandwidth 80.0 Gbps. DisplayPort's home mode lacks some HDMI features, such as Consumer Electronics Control (CEC) commands. The CEC bus allows you to link multiple sources to a single display and control any of these devices from any remote control. DisplayPort 1.3 added the ability to transfer CEC commands via AUX from its first version of the HDMI CEC function to support multiple sources connected to a single display, as is typical of the TV screen. On the contrary, Multi-Stream Transport allows you to connect multiple displays to one computer source. This reflects the facts that HDMI originated from consumer electronics companies while DisplayPort is owned by VESA, which started out as an organization for computer standards. HDMI can take much longer maximum cable length than DisplayPort (30 meters vs. 3 meters). HDMI uses the unique structure of the Supplier-Specific Block block, which allows you to use features such as additional color spaces. However, these features can be defined by CEA EDID extensions. (quote needed) HDMI and DisplayPort have published the signal specification through the USB-C connector. For more information see IDC market share figures showing that 5.1% of commercial desktops and 2.1% of commercial laptops released in 2009 featured DisplayPort. The main factor of this was the phased release of the VGA, and Intel and AMD planned to stop creating products with FPD-Link by 2013. According to Digitimes Research, almost 70% of LCD monitors sold in August 2014 in the United States, THE United Kingdom, Germany, Japan and China were equipped with HDMI/DisplayPort technology, which is 7.5% more than last year. IHS Markit predicts that DisplayPort will surpass HDMI in 2019. Standards Companion Mini DisplayPort Main article: Mini Mini Mini DisplayPort (mDP) is the standard announced by Apple in the fourth quarter of 2008. Shortly after the announcement of the Mini DisplayPort, Apple announced that it would license connector technology without a fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification. On February 24, 2011, Apple and Intel announced Thunderbolt, the successor to Mini DisplayPort, which adds support for the PCI Express data connection while maintaining backward compatibility with mini DisplayPort- based peripherals. Micro DisplayPort Micro DisplayPort will have targeted systems that need ultra-compact connectors such as phones, tablets and ultra-portable laptops. This standard would be physically smaller than the currently available Mini DisplayPort connectors. The standard was expected to be released in the second quarter of 2014. DDM Direct Drive Monitor (DDM) 1.0 was approved in December 2008. This allows controller-less monitors where the display panel is directly controlled by the DisplayPort signal, although the available resolution and color depth are limited to two-lane operation. The Compression Compression Compression Display Display (DSC) is a VESA developed by a low-latency compression algorithm to overcome the limitations associated with sending high-resolution video to physical limited bandwidth tools. It is a visually loss-free low latency algorithm based on PCM delta coding and YCoCg-R color space; This allows you to increase the resolution and depth of color and reduce energy consumption. The DSC has been tested to meet the requirements of the ISO/IEC 29170-2 evaluation procedure for near-loss coding using various test models, noise, subpixel text (ClearType), user interface captures, and photo and video images. DSC version 1.0 was released on March 10, 2014, but was soon unmalighted by version of DSC 1.1, released on August 1, 2014. The DSC standard supports up to 3:1 compression ratio with constant or variable bit frequency, 4:4:4 chrome sub-write, optional 4:2:2 conversions and 6/8/10/12 bits per color component. DSC version 1.2 was released on January 27, 2016 and is included in DisplayPort 1.4; Version 1.2a was released on January 18, 2017. The update includes native coding of formats 4:2:2 and 4:2:0 in pixel containers, 14/16 bits per color and minor changes in the coding algorithm. The DSC compression works on a horizontal line of pixels encoded using groups of three consecutive pixels for native 4:4:4 formats and simple 4:2:2 formats, or six pixels (three compressed containers) for native formats 4:2:2 and 4:2:0. If RGB coding is used, it is first converted to reversible YCgCo. Simple conversion from 4:2:2 to 4:4:4 Add the missing chromium samples by interpolating the adjacent pixels. Each component of the lusma is kod separately using three independent sub-flows (four sub-flows in the Mode). The forecasting step is performed using one of three modes: a modified medium adaptive coding algorithm (MMAP), similar to the algorithm used by JPEG-LS, block prediction (optional for decoders due to the high computational complexity agreed upon when shaking the DSC), and the average prediction point. The bit speed control algorithm tracks the color plane and the fullness of the buffer to adjust the depth of the quantitative bit for the pixel group in a way that minimizes compression artifacts while remaining within the bitrate. Repetition of the last pixels can be stored in the 32-entry color index history buffer (ICH), which can be referenced directly by each group in the slice; This improves the quality of compression of computer images. In addition, prediction residues are calculated and encoded using an entropy entropy entropy entropy entropy entropy coding algorithm based on delta-alter length unit coding (DSU-VLC). Coded pixel groups are combined into pieces of varying heights and widths; common combinations include 100% or 25% image width, and 8-, 32-, or 108-line height. On January 4, 2017, IT announced HDMI 2.1, which supports a resolution of up to 10K and uses DSC 1.2 for video, which is above 8K resolution with a 4:2:0 chrome sub-network. eDP Embedded DisplayPort (eDP) is the standard display panel interface for portable and built-in devices. It identifies the alarm interface between graphics cards and integrated displays. Various eDP changes are based on existing DisplayPort standards. However, the version numbers between the two standards are not interchangeable. For example, eDP 1.4 is based on DisplayPort 1.2, while eDP 1.4a is based on DisplayPort 1.3. In practice, the built-in DisplayPort has supplanted LVDS as the dominant panel interface in today's laptops. eDP 1.0 was adopted in December 2008. It included advanced energy-saving features such as seamless upgrade speed switching. Version 1.1 was approved in October 2009 and then version 1.1a in November 2009. Version 1.2 was approved in May 2010 and includes DisplayPort 1.2 HBR2 data speed, consecutive 120Hz color monitors and a new display panel control protocol that runs through the AUX channel. Version 1.3 was published in February 2011; It includes a new additional Self-Refresh (PSR) feature designed to save the system's energy and further extend battery life in portable PC systems. PSR mode allows the GPU to enter energy-saving states in between frame updates, including a memory framebuffer in the display panel controller. Version 1.4 was released in February 2013; it reduces energy consumption by partially updating staffing PSR mode, regional backlight management, lower-voltage interface and additional communication tariffs; The auxiliary channel supports data with a lot of touch panels to accommodate various form factors. Version 1.4a was published in February 2015; The base version of DisplayPort has been updated to to support HBR3 data rates, 1.1 display flow compression, segmented panel displays, and partial updates to the Self-Refresh panel. Version 1.4b was published in October 2015; its refinement and refinement protocol is designed to ensure the adoption of eDP 1.4b in devices by mid-2016. The internal iDP (iDP) 1.0 display was approved in April 2010. The iDP standard identifies the internal connection between the digital TV system on the chip controller and the display panel synchronization controller. It aims to replace the current internal FPD-Link lanes with the DisplayPort connection. IDP has a unique physical interface and protocols that are not directly compatible with DisplayPort and are not applicable to external connectivity, but they provide very high resolution and upgrade speed while providing simplicity and capability. The IDP has a non-variable 2.7GHz clock and is nominally estimated at 3.24 Gbps per lane, with up to sixteen lanes in the bank, resulting in a six-fold reduction in wiring requirements compared to the FPD-Link for signal 1080p24; other data transmissions are also possible. iDP was built with simplicity in mind, so does not have an AUX channel, content protection or multiple threads; It does, however, frame sequential and line intertwined stereo 3D. PDMI Portable Digital Media Interface (PDMI) is a connection between docking/display devices and portable media players that includes a 2-band DisplayPort v1.1a connection. It was ratified in February 2010 as ANSI/CEA-2017-A. wDP Wireless DisplayPort (wDP) provides bandwidth and a set of DisplayPort 1.2 features for cable applications running in the 60GHz radio range. It was announced in November 2010 by WiGig Alliance and VESA as a collaboration. The SlimPort A SlimPort-to-HDMI adapter made by Analogix SlimPort, the Brand of Analogix products, corresponds to Mobility DisplayPort, also known as MyDP, which is the industry standard for mobile audio/video interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements video transmission to 4K-UltraHD and up to eight audio channels through the micro-USB connector. SlimPort products provide seamless connectivity to DisplayPort, HDMI and VGA displays. MyDP was released in June 2012, and the first product that SlimPort used was Google's Nexus 4 smartphone. Some LG series LG G smartphones have also adopted SlimPort. SlimPort is an alternative to the high-definition mobile link (MHL). The main article of DisplayID: DisplayID DisplayID is designed to replace the E-EDID standard. DisplayID has variable length structures that cover all existing EDID extensions, as well as new extensions for 3D displays and built-in displays. version 1.3 (announced 23 23 2013) adds extended support to topology tile displays; This allows you to better identify multiple video streams, as well as reports of the size of the bezel and location. As of December 2013, many modern 4K displays use tile topology, but do not have a standard way to tell the video source which tile is left and which right. These early 4K displays, for manufacturing reasons, typically use two 1920×2160 panels laminated together and are now generally treated as multiple monitor installations. DisplayID 1.3 also allows 8K to display the opening, and has applications in 3D stereo that use multiple video streams. DockPort Main: DockPort DockPort, formerly known as Lightning Bolt, is a continuation of DisplayPort to include USB 3.0 data as well as the power to charge portable devices with attached external displays. Originally developed by AMD and Texas Instruments, it was announced as a VESA specification in 2014. The main USB-C article: USB-C on September 22, 2014, VESA published an alternative DisplayPort mode on USB Type-C Connector Standard, a specification on how to send DisplayPort signals through the recently released USB-C connector. One, two or all four differential pairs that USB uses for a SuperSpeed bus can be configured dynamically for use for DisplayPort lanes. In the first two cases, the connector can still carry a full SuperSpeed signal; In the latter case, at least no SuperSpeed signal is available. The DisplayPort AUX channel is also supported by two side lane signals in the same connection; In addition, USB Power Delivery is possible simultaneously in accordance with the recently expanded USB-PD 2.0 specification. This makes the Type-C connector a strict superset of usage cases provided for DockPort, SlimPort, Mini and Micro DisplayPort. VirtualLink: VirtualLink VirtualLink is a offering that allows you to deliver virtual reality headsets one by one USB-C cable. Products of the two-mode DisplayPort connector since its introduction in 2006, DisplayPort has gained popularity in the computer industry and featured on many graphics cards, displays and laptops. Dell was the first company to introduce a consumer product with a DisplayPort connector, the Dell UltraSharp 3008WFP, which was released in January 2008. Shortly thereafter, AMD and Nvidia released products to support the technology. AMD included support in the Radeon HD 3000 graphics series, while Nvidia first introduced support in the GeForce 9 series, starting with the GeForce 9600 GT. The new connector - its own at the time - eventually became part of the DisplayPort standard, but Apple reserves the right to revoke the license licensee to launch a patent infringement lawsuit against Apple. In 2009, AMD followed suit with the Radeon HD 5000 Graphics Card Series graphics cards, which included Mini DisplayPort in the Eyefinity versions in the series. On November 4, 2015, Nvidia released the NVS 810 with 8 Mini DisplayPort outputs on one map. On May 6, 2016, Nvidia showed the GeForce GTX 1080, the world's first DisplayPort 1.4-enabled graphics card. On June 29, 2016, AMD followed the Radeon RX 480 to support DisplayPort 1.3/1.4. The Radeon RX 400 series will support DisplayPort 1.3 HBR and HDR10 by dropping the DVI connector (s) in the help board design. In February 2017, VESA and qualcomm announced that DisplayPort Alt Mode video transport will be integrated into the Snapdragon 835 mobile chipset, which powers smartphones, VR/AR head displays, IP cameras, tablets and mobile PCs.

The display device stereo display (also 3D display) is a display device capable of transmitting depth perception to the viewer using stereopsis for binocular vision. Types - Stereoscopy vs. 3D The basic technique of stereo displays is to present offset images that are displayed separately on the left and right eye. Both of these 2D image displacements are then combined in the brain to give a perception of 3D depth. Although the term 3D is widely used, it is important to note that the representation of double 2D images is distinctly different from the display of an image in three complete dimensions. The most noticeable difference from real 3D displays is that the movements of the observer's head and eyes do not increase information about the three-dimensional objects displayed. For example, holographic displays do not have such restrictions. Just as in sound playback it is impossible to recreate a complete three-dimensional sound field with only two stereophonic speakers, it is also an exaggeration of the ability to refer to dual 2D images as 3D. The exact term stereoscopic is more cumbersome than the common wrong 3D name, which has taken root after many decades of undeniable abuse. It should be noted that while most stereoscopic displays do not qualify as a real 3D display, all real 3D displays also have stereoscopic displays because they meet lower criteria as well. Stereo displays The main article: Stereoscopy Based on stereopsis principles described by Sir Charles Wheatstone in the 1830s, stereoscopic technology provides a different image of the viewer's left and right eye. Below are some technical details and methodology used in some of the most notable stereoscopic systems that have been developed. Side-by-side images of The Early Bird Catches Worm Stereograph published in 1900 by The Northwest View of Koh Barabu, Wisconsin, digitally restored. Traditional stereoscopic photography consists of creating a 3D illusion, starting with a pair of 2D images, stereograms. The easiest way to improve the perception of depth in the brain is to provide the viewer's eyes with two different images representing two viewpoints of the same object, with a slight deviation exactly equal to the perspective that both eyes naturally get into binocular vision. If you avoid eye tension and distortion, each of the two 2D images should preferably be presented to each eye of the viewer, so that any object at an infinite distance, seen by the viewer, is perceived by this eye, while it is oriented directly forward, the viewer's eyes do not intersect and diverge. When does not contain an object at an infinite distance, such as a horizon or cloud, the images should be closer to each other. The method side-by-side is extremely easy to create, but it can be difficult or inconvenient to view without optical means. Stereoscope and Stereographic Maps Main Article: Stereoscope Stereoscope is a device for viewing stereographic maps that are maps that contain two separate images that are printed side by side to create the illusion of a three-dimensional image. Transparency Viewers Home article: Slide viewing stereo slide viewing View-Master Model E 1950s Pairs of stereo views printed on a transparent base are considered transmitted light. One advantage of viewing transparency is the ability for a wider, more realistic dynamic range than is practical with prints on an opaque basis; the other is that a wider field of view can be represented, as images illuminated from behind can be placed much closer to the lenses. The practice of watching a film based on stereoscopic transparency dates back to at least 1931, when Tru-Vue began selling sets of stereo views on 35mm film strips that were powered through the viewer's hand-held Bakelite. In 1939, a modified and miniature variation of this technology was presented as a View-Master, using cardboard discs containing seven pairs of small codechrom color films. The head set displays the main article: The head installed display and the virtual retina display The user usually wears a helmet or glasses with two small LCD or OLED displays with magnifying lenses, one for each eye. The technology can be used to display stereofilms, images or games. Head displays can also be connected to head-tracking devices, allowing the user to view the virtual world by moving their head, eliminating the need for a separate controller. With rapid advances in computer graphics and the continued miniaturization of video and other hardware, these devices are starting to become available at a smarter price. Head or wearable glasses can be used to view an end-to-end image imposed on the real worldview, creating so-called augmented reality. This is done by reflecting video images through partially reflective mirrors. The real world can be seen through a partial mirror. The recent development of holographic-wave guides or wave optics allows stereoscopic images to be superimposed on the real world without the use of a bulky reflective mirror. Head-mounted projection displays (HMPD) are similar to displays mounted on the head, but with images projected and displayed on a retro reflective screen, the advantage of this technology over installed on the The display is that focus and face problems do not require fixation with corrective eye lenses. Pico projectors are used to generate images instead of LCD or OLED screens. Alagliph Home article: Anaglyph 3D Archetypal Archetypal glasses, with modern red and blue color filters similar to red/green and red/blue lenses used to view early anaglyphic films. In anaglyph, these two images are superimposed into an additive light installation through two filters, one red and one blue. In the light subtraction settings, these two images are printed in the same additional colors on white paper. Glasses with color filters in each eye separate the appropriate image, canceling the color of the filter and making an additional black color. The compensating method, commonly known as Anachrome, uses a slightly more transparent cyanide filter in patented glasses related to the technique. The process reconfigures a typical anaglyph image to have less parallax. An alternative to the usual system of red and cyanide anagliph filters is ColorCode 3-D, a patented anaglyph system that was invented to present an anaglyph image in conjunction with the NTSC television standard, in which the red channel is often compromised. ColorCode uses additional colors of yellow and dark blue on the screen, and the colors of the lenses of the glasses are amber and dark blue. Polarization systems resembling sunglasses, round polarized RealD glasses are now the standard for theatrical releases and theme park rides. Main article: Polarized 3D system To represent a stereoscopic pattern, two images are projected onto one screen through different polarizing filters. The viewer wears glasses that also contain a pair of polarizing filters oriented differently (clockwise/counterclockwise with circular polarization or at a 90 degree angle, usually 45 and 135 degrees, with linear polarization). Because each filter passes only that light that is similarly polarized and blocks the light polarized differently, each eye sees a different image. It is used to produce a three-dimensional effect by projecting the same scene into both eyes, but is depicted from several different angles. In addition, since both lenses have the same color, people with one dominant eye, where one eye is used more, can see the colors properly, previously negated by the separation of the two colors. Circular polarization has an advantage over linear polarization, in that the viewer does not need to have the head vertically and aligned with the screen for polarization to work properly. With linear polarization, turning the points to the side causes the filters to come out of the alignment with the screen filters, causing the image to disappear and making it easier for each eye to see the opposite frame. For circular polarization, the polarizing effect works no matter how the viewer's head is aligned with the screen, for example, tilted to the side or even upside down. The left eye will be see only the image intended for it, and vice versa, without fading or cross-talking. Polarized light reflected from normal motion the screen usually loses most of its polarization. Therefore, it is necessary to use an expensive silver screen or aluminum screen with a slight loss of polarization. All types of polarization will result in blackouts of the displayed image and a worse contrast than non-3D images. Light from lamps usually radiates as a random collection of polarization, while the polarization filter passes only a fraction of the light. As a result, the screen image is darker. This darkening can be compensated by an increase in the brightness of the projector's light source. If the initial polarization filter is inserted between the lamp and the image generation element, the intensity of the light that affects the image is no higher than normal without a polarizing filter, and the overall contrast of the image transmitted to the screen does not affect. The Eclipse Method is a pair of LCD shutter glasses used to view XpanD 3D films. Thick frames hide electronics and batteries. Main article: Active Shutter 3D System With Eclipse Method, shutter blocks light from each corresponding eye when the image of the reverse eye is projected on the screen. The display alternates between left and right images, and opens and closes the shutters in glasses or the viewer in sync with the images on the screen. This was the basis of the Teleview system, which was briefly used in 1922. A variation of the eclipse method is used in lcd shutters. Glasses containing a liquid crystal that will allow light through in sync with images on the screen of a movie theater, television or computer, using the concept of alternative frame sequence. This is the method used by nVidia, XpanD 3D and earlier IMAX systems. The downside of this method is the need for every viewing person to wear expensive, electronic glasses that must be synchronized with the display system using a wireless signal or attached wire. Shutter-glasses are heavier than most polarized glasses, although lightweight models are no heavier than some sunglasses or luxurious polarized glasses. However, these systems do not require a silver screen for projected images. The valves of liquid crystal light work by rotating light between two polarizing filters. Because of these internal polarizers, LCD shutter-glasses obscure the display image of any LCD, plasma, or projector image, which has the result that the images seem dim and contrast lower than for normal non-3D viewing. This is not necessarily a usage issue; For some types of displays that are already very bright with poor grayish-black levels, LCD shutter glasses can really improve image quality. Interference filter technology Main article: Anaglyph 3D - Dolby 3D Interference Filter Systems uses specific wavelengths of red, green and for the right eye, as well as different wavelengths of red, green and blue for the left eye. Glasses that filter out very specific specific allow the wearer to see a 3D image. This technology eliminates the expensive silver screens needed for polarized systems such as RealD, which is the most common 3D display system in cinemas. This, however, require much more expensive glasses than a polarized system. It is also known as spectral combing filtering or wavelength multiplex imaging recently introduced Omega 3D/Panavision 3D system also uses this technology, albeit with a wider range and more teeth on the crest (5 for each eye in the Omega/Panavision system). Using more spectral bands on the eye eliminates the need for the color image process required by the Dolby system. The even separation of the visible spectrum between the eyes gives the viewer a more relaxed feeling as the light energy and color balance is almost 50-50. Like the Dolby system, omega can be used with white or silver screens. But it can be used with film or digital projectors, unlike Dolby filters, which are only used in a digital system with a color correction processor provided by Dolby. The Omega/Panavision system also claims that their glasses are cheaper to manufacture than those used by Dolby. In June 2012, omega 3D/Panavision's 3D system was discontinued by DPVO Theatrical, which launched it on behalf of Panavision, citing challenging global economic and 3D market conditions. Despite the fact that DPVO has dissolved its business operation, Omega Optical continues to promote and sell 3D systems to non-theatrical markets. Omega Optical's 3D system contains projection filters and 3D glasses. In addition to the passive stereoscopic 3D system, Omega Optical has released improved anaglyph 3D glasses. Omega red/cyanide anaglyph glasses use sophisticated metal oxide thin film coatings and high-quality annotated glass optics. Autostereoscopy Home article: Nintendo 3DS Autosterescopy uses parallax barrier autosterescopy to display 3D images. In this method, glasses don't have to see a stereoscopic image. Lenticular lenses and parallax barrier technologies include overlaying two (or more) images on one sheet, in narrow, alternating stripes, and using a screen that either blocks one of the bands of the two images (in the case of parallax barriers), or uses equally narrow lenses to bend the stripes of the image and make it appear to fill the entire image (in the case of lenticular imprints). To produce a stereoscopic effect, a person must be positioned so that one eye sees one of the two images and the other sees the other. Optical principles of multi-type auto-stereoscopy have been known for more than a century. Both images on a highly heated corrugated screen that reflects light at an acute angle. In order to see the stereoscopic image, the viewer must sit at a very narrow angle, which is almost perpendicular to the screen, limiting the size size Lenticular was used for the theatrical presentation of numerous short films in Russia from 1940 to 1948 and in 1946 for the feature film Robinson Crusoe, although its use in theatrical presentations was rather limited, lenticularly widely used for various novelties and even used in amateur 3D photography. Recent use includes Fujifilm FinePix Real 3D with autostereoscopic display, which was released in 2009. Other examples of this technology include autostereoscopic LIQUIDCR displays on monitors, laptops, TVs, mobile phones and gaming devices such as The Nintendo 3DS. Other methods Main article: Stereoscopy random point outsterogram encodes a 3D scene that can be seen with proper autostereogram viewing techniques is a single image stereogram (SIS), designed to create a visual illusion of a three-dimensional (3D) scene from a two-dimensional image in the human brain. In order to perceive 3D forms in these outstereograms, the brain must overcome the usually automatic coordination between focus and face. The Pulphrich effect is a psychophysical perception where the lateral movement of the object in the field of vision is interpreted by the visual cortex as having a depth component, due to the relative difference in signal timing between the two eyes. Prismatic glasses make cross-viewing easier, and more/under viewing possible examples include browsing CMH. Wiggle Stereoscopy is a method of displaying an image achieved by quickly alternating the display of the left and right sides of the stereogram. Found in animated GIF format on the Internet. Real 3D 3D 3D displays display the image in three full dimensions. The most noticeable difference from stereoscopic displays with only two 2D offset images is that the movement of the observer's head and eyes will increase information about the three-dimensional objects displayed. Volumetric Display Home Article: Volumetric Display Volumetric 3D Display Volumetric Displays use some physical mechanisms to display points of light in volume. These displays use voxels instead of pixels. Volume displays include a multiplanarian display that has several folded display planes, and rotating display panels where the rotating panel sweeps out the volume. Other technologies have been developed for the project project of light points in the air above the device. The infrared laser focuses on the destination in space, creating a small plasma bubble that emits visible light. Holographic Displays Main Articles: Holographic display and computer holographic display is a display technology that has the ability to provide all four eye mechanisms: binocular inequality, movement parallax, placement and 3D objects can be viewed without any special glasses and no visual fatigue will be caused by human eyes. In 2013, Silicon Valley Company LEIA Inc Inc. The production of holographic displays is well suited to mobile devices (watches, smartphones or tablets) using multi-direction lighting and allowing a wide full parallax angle of view to see 3D content without the need for glasses. Integral imaging: Integral imaging Integral image is an autostereoscopic or multiscopic 3D display, which means that it displays a 3D image without the use of special glasses on the part of the viewer. This is achieved by placing an array of microlins (similar to a lenticular lens) in front of an image where each lens looks different depending on the angle of view. So instead of displaying a 2D image that looks the same on all sides, it reproduces a 4D light field, creating stereo images that show parallax when the viewer moves. A compressed light field displays a new display technology called a compressed light field currently being developed. These prototypes display the use of layered liquid crystal panels and compression algorithms during display. Designs include dual- and multi-layered devices that are controlled by algorithms such as computed tomography and non-nuclear matrix factoring and non-nuclear factoring of tensor. The problems of each of these display technologies can be seen to have limitations, whether it is the viewer's location, bulky or unsightly equipment or the high cost. Displaying 3D images without artifacts remains difficult. (quote is necessary) References : The new holographic wave wave complements reality.
