In the men's connector, this pin code corresponds to a wired and solder cable. The Video Graphics Array (VGA) connector is the standard connector used to display video. Emerging with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector has become ubiquitous on PCs, as well as many monitors, projectors and high-definition TVs. Other connectors have been used to carry VGA-compatible signals such as the mini-VGA or BNC, but the VGA connector usually refers to this design. Devices continue to be manufactured with VGA connectors, although new digital interfaces such as DVI, HDMI and DisplayPort are increasingly displacing VGA, and many modern computers and other devices do not include it. The physical design of the vGA connector represents a 3-row, 15-pin D-subminature connector, called a different HOW DE-15, HD-15 or DB-15. The DE-15 is the most accurate overall item according to the D-sub specifications: a D-sub- size E connector with 15 pins in three rows. Electric Design All VGA connectors carry analog RGBHV (red, green, blue, horizontal synchronization, vertical synchronization) video signals. Modern connectors also include VESA DDC contacts, to identify the attached display devices. In both modern and original versions, the VGA uses multiple scanning rates, so such as monitors are multisync as needed. The VGA interface does not include hot replacement capabilities, the ability to connect or disable a output device while working, although in practice this can be done and does not normally cause damage to equipment or other problems. The VESA DDC specification, however, includes a standard for hot replacement. PS/2 alarms In the original implementation of the IBM VGA, the upgrade speed was limited to two vertical (60 and 70 Hz) and three horizontal frequencies, all of which were brought to the monitor using combinations of different signals of synchronization of the polarity H and V. Some pins on the connector also differed: Pin 9 was the key, plugging the female connector, and four pins carried the monitor. Devices that meet the standard of the host DDC system provide 5 V ± 5%, from 50 mA to 1 A.8.8PS/55, signaling THE IBM PS/55 Display Adapter, a redefined pin 9 as 12V, which signals the monitor to turn on when the system block is turned on. Cable quality VGA cable with DE-15 men's connector Same VGA cable can be used with various supported VGA resolutions ranging from 320×400px 70Hz, or 320×480px 60 Hz (12.6 MHz signal capacity) to 1280×1024px (SXGA) 85 Hz (160 MHz) and up to 2048×1536px (GGA) 85 Hz (388 MHz). There are no standards for the quality required for each resolution, but better cables usually contain coaxial wiring and insulation that make them thicker. While shorter VGA cables are less likely to cause significant signal degradation, a quality cable should not suffer from a cross-conversation signal (in which signals in a single wire cause unwanted currents in adjacent wires) even longer. The ghost occurs when impedance inconsistencies cause signals to be reflected. The correct coincidence of the cable (75 om) should prevent this, however, the ghost with long cables can be caused by equipment with incorrect signal termination or passive cable splitters, rather than the cables themselves. Alternative VGA BNC connectors Some high-end monitors and graphics cards use multiple BNC connectors instead of a single standard VGA connector, providing a higher quality connection with less cross-conversation using five separate 75 ohm coaxial cables. In a 15-pin connector, red, green and blue signals (contacts 1, 2, 3) cannot be protected from each other, so cross-conversation is possible within a 15-pin connection. BNC prevents cross-talk by maintaining full coaxial shielding through circular connectors, but the connectors are very large and bulky. Requiring you to press and rotate the plug shell to disconnect requires space around around connector to grab every shell of the BNC fork. Additional signals such as DDC are generally not supported by BNC. The Mini-VGA port on the Mac laptop And other small devices use a two-row mini-VGA connector that is much smaller than the 3-row DE-15 connector or 5 separate BNC connectors. Adapters Different adapters can be purchased to convert VGA into other types of connectors. One common variety is the DVI for VGA adapter, which is possible because many DVI interfaces also carry VGA-compatible analog signals. Adaptation from HDMI to VGA is not directly possible, as HDMI does not contain an analog signal. Converting to digital formats such as HDMI and DVI requires a scanning converter. VGA outputs on interfaces with different signal, more complex converters can be used. Most of them need an external source of power to work and are inherently unprofitable. However, many modern displays are still made with multiple inputs, including the VGA, in which case the adapters are not necessary. The VGA can also be adapted to SCART in some cases because the signals are electrically compatible if the correct synchronization rates are set by the host PC. Many modern graphics adapters can change their signal in software, including upgrade speed, synchronization length, polarity, and number of empty lines. Specific issues include interracial support and the use of Resolution 720×576 in THE PAL countries. In these restrictive conditions, a simple enough scheme can be used to combine VGA synchronization signals into SCART composite synchronization. Extenders A VGA Extender is an electronic device that increases the signal strength from the VGA port, most often from a computer. They are often used in schools, businesses and homes when multiple monitors currently run one VGA port, or if the cable between the monitor and computer will be excessively long (often photos appear blurry or minor artifacts if the cable goes too far without a steering wheel). VGA extenders are sometimes referred to as VGA accelerators.

The terminology here is sometimes used quite interchangeably when it comes to labeling different types of VGA cable and be a little vague. However, the main or standard type of VGA connector is usually referred to as some variant of the following: DE-15, HD15, VGA plug-in, SVGA connector, D-Sub 15 or D-Subminiature, or more common RGB connector.

Signal quality starts to fall above 1920x1080 (1080p), which will result in a drop in image quality due to the analog nature of the signal, but with a reasonably good cable and transceiver at both ends it can be used for resolutions up to and including 2048x1536.
