ATI, graphics product group of Advanced Micro Devices, said on Wednesday that its ATI Radeon graphics adapters conform to the Video Electronics Standards Association (VESA) first DisplayPort certification. The VESA DisplayPort Certified logo should assure customers that DisplayPort products interoperate and provide problem free experience.

The certification has been awarded to the ATI Radeon HD 3400, ATI Radeon HD 3600 and ATI Radeon HD 3800 graphics products, and the AMD 780G integrated graphics chipset.

“AMD is proud to be recognized with the selection of the ATI Radeon HD 3000 series and AMD 780G integrated graphics chipset as the first certified source devices for DisplayPort. This certification gives PC consumers next-generation display capabilities today,” said Matt Skynner, vice president of marketing, Graphics Products Group, AMD.

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.

DisplayPort incorporates a Main Link, a high-bandwidth, low-latency, unidirectional connection supporting isochronous stream transport. One stream video with associated audio is supported in Version.1.0, but DisplayPort is seamlessly extensible, enabling support of multiple video streams. Version 1.0 also includes an Auxiliary Channel to provide consistent-bandwidth, low-latency, bi-directional connectivity with Main Link management, and device control based on VESA’s E-DDC, E-EDID, DDC/CI and MCCS standards. The Link configuration enables true “Plug-and-Play”. The Main Link bandwidth enables data transfer at up to 10.8Gb/s using a total of four lanes. 

DisplayPort 1.1 adds support for high bandwidth digital content protection (HDCP) version 1.3 and also provides for low voltage and low power operation, and enables improved interoperability and reduced EMI through its embedded clock architecture. 

Earlier this month  Video Electronics Standards Association (VESA) announced that Allion Test Labs, via its Taiwan facility, has been approved to offer compliance testing for the DisplayPort standard. Allion is the first test center approved to test DisplayPort products to ensure that they meet the DisplayPort standard requirements. Compliant products are able to display the DisplayPort Certified Logo. This logo that tells consumers the products have been tested to meet the DisplayPort standard. All compliant products will be listed at Displayport.org. At press time there were no AMD products listed on the official web-site of DisplayPort.
