Whether it is in the form of an external desktop monitor, a notebook’s embedded panel, or the touch screen of a PC tablet, display devices play a vital role in defining the user’s visual experience. The new display technologies integrated into the AMD Radeon™ HD 6800 series GPUs are targeted to deliver pristine image quality and impressive performance in three different technologies: Multi-display Technologies DisplayPort 1.2, a new display interface, boasts features such as higher bandwidth and daisy- chaining capabilities. Combined, these features complement the AMD Eyefinity1 multi-display technology very well. Stereoscopic 3D The introduction of high refresh rate LCD panels (120Hz and higher) have inspired new stereoscopic 3D display devices for the PC and the CE markets. This whitepaper will explain how the new AMD Radeon™ HD 6800 series GPUs enables the PC to deliver a cinematic stereoscopic 3D experience. Wide Color Gamut Monitors and notebook with wide color gamut panels, once reserved for the professional market, have become more prominent with several products shipping in the market. While these types of LCD panels display a wider range of colors, the drawbacks and challenges will be explained in this whitepaper, as well as the color gamut remapping technology integrated in the AMD Radeon™ HD 6800 series GPUs. This whitepaper provides an overview of the capabilities and display technologies integrated into the AMD Radeon™ HD 6800 series GPUs display engine. These capabilities and technologies, when combined with cutting edge display devices, deliver the ultimate visual experience. 1 AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. AMD Eyefinity technology can support up to 6 displays using a single enabled AMD Radeon™ graphics card with Windows Vista or Windows 7 operating systems – the number of displays may vary by board design and you should confirm exact specifications with the applicable manufacturer before purchase. SLS (“Single Large Surface”) functionality requires an identical display resolution on all configured displays. ©2010 Advanced Micro Devices, Inc., the AMD logo, Radeon, and The Ultimate Visual Experience are trademarks of Advanced Micro Devices, Inc.

AMD Radeon™ HD 6800 Series Display Technologies 3 DISPLAYPORT™ 1.2 In 2006, PC manufacturers (including AMD) collaborated in designing the next generation PC display interface, which would eventually be known as DisplayPort. DisplayPort was designed to replace DVI and VGA by offering features that are beneficial to both system integrators and end users. It was also designed to be flexible and easily extensible for new features that the market will require in the future. The first generation of DisplayPort provided over 10.8 Gbps of raw bandwidth, which no other display interface could match. DisplayPort also supported very long non-active cables, optional latch designs for connectors, and audio support. In addition, with DisplayPort spread spectrum clocking can be enabled to reduce EMI, and source devices such as GPUs can operate in dual-mode. The latter is valuable for it allows the same connector to transport TMDS signals to support DVI and HDMI outputs using inexpensive level-shifting adapters. The data link rates of DisplayPort 1.1a are fixed at either 1.62 Gbps per lane or 2.7 Gbps per lane, irrespective of the timing of the attached display device. This design only requires a single reference clock source to drive as many DisplayPort streams as there are display pipelines in the GPU. In contrast, DVI and HDMI both require a dedicated clock source per display timing. This unique DisplayPort feature allows for the most efficient multi-display design and complements the AMD Eyefinity technology. Please refer to the AMD Eyefinity Technology Brief for more information. All the features of DisplayPort 1.1a proved that it was the superior PC display interface. To further enhance the DisplayPort interface, the same group of companies collaborated once more to define the next version of DisplayPort, which paved the way to DisplayPort 1.2. In early 2010, the DisplayPort 1.2 specification was ratified in VESA. This new revision of the standard adds support for new and exciting features including High bit-rate audio, even higher bandwidth, and multi-streaming capabilities. Just as AMD was the first to integrate DisplayPort technology into GPUs with the ATI Radeon™ HD 3000 series, the AMD Radeon™ HD 6800 series graphics will be the pioneer GPUs designed to support DisplayPort 1.2 features. Table 1 is a simplified comparison of display interface capabilities integrated into AMD Radeon™ HD 6800 series GPUs: DisplayPort 1.2 DisplayPort 1.1a SL-DVI DL-DVI HDMI 1.4a Bandwidth 21.6 Gbps 10.8 Gbps 4.95Gbps 9.9 Gbps 6.75 Gbps Video Data Rate 17.28 Gbps 8.64 Gbps 3.96 Gbps 7.92 Gbps 5.4 Gbps Maximum Resolution Support @ 60Hz >2560x2048 2560x2048 1920x1200 2560x1600 1920x1200 24bpp Audio Support Yes Yes No No Yes Embedded Application Yes Yes No No No Support In-band Stereo 3D Yes Yes No No Yes signaling Multi-stream support Yes No No No No Table 1: Display interface capabilities of the AMD Radeon™ HD 6800 series GPUs ©2010 Advanced Micro Devices, Inc., the AMD logo, Radeon, and The Ultimate Visual Experience are trademarks of Advanced Micro Devices, Inc.

AMD Radeon™ HD 6800 Series Display Technologies 4 High Bit-rate 2 DisplayPort 1.2 supports up to twice the bandwidth of DisplayPort 1.1a. High Bit-rate 2 (HBR2) provides up to 5.4 Gbps/lane of bandwidth, or up to 21.6 Gbps in a full four lane configuration. This lends itself very well to many applications that require ultra-high bandwidth. Chart 1 illustrates the wide range of display timings (resolution, refresh rate, and color depth) supported by various digital display interfaces. Chart 1: Comparison
