Advanced Micro Devices on Wednesday said its ATI Radeon graphics processor has passed interoperability testing with DisplayPort 1.1 interface. The company did not unveil which chip was used, but the announcement still emphasizes that ATI, graphics product group of AMD, is ready with its DisplayPort-compliant product.

The testing was completed with a Genesis Microchip DisplayPort 1.1 receiver. AMD is currently attending the Video and Electronics Standards Association (VESA) PlugTest in Milpitas, California to undergo further interoperability testing.

“AMD has been driving the high-definition transition on the PC with innovative firsts such as integrated HDMI, high-bandwidth digital content protection (HDCP) and our Unified Video Decoder (UVD). With the successful interoperability testing of the first graphics chip to feature a native DisplayPort transmitter, we are once again breaking new ground in customer-centric innovation by offering increased choice in video and display technologies to our users,” said Rick Bergman, senior vice president and general manager, graphics products group, AMD.

Even though the company did not unveil which graphics processor was used for interoperability testing, the firm indicated that DisplayPort interfaces are expected to be natively supported in ATI Radeon graphics processors in the early 2008 timeframe, which means that the company may already have functional products it plans to release in early 2008.

The DisplayPort is designed to enable a common interface approach across both internal and external display connections. Internal connections include display interfaces within a notebook PC or within an LCD display. External display connections include the interface between a source device such as a desktop PC, set-top box, DVD player or game console, and a display device such as a direct view flat panel or projection display for viewing video and graphics. The DisplayPort standard will also include an optional digital audio capability allowing streaming of high definition digital audio-video content over the interface, and provides performance scalability to enable the next generation of displays featuring higher color depths, refresh rates, and display resolutions.
