The Video Electronics Standards Association (VESA) announced last week its plans to launch a DisplayPort cable adaptor verification program. DisplayPort cable adaptors allow a DisplayPort interface to connect with other video interface types such as DVI, HDMITM or VGA, providing consumer devices compatibility as the PC industry transitions to DisplayPort.

VESA will initially offer verification testing for Source-side DP-to-DVI and DP-to-HDMI cable adaptors, due to their popularity and importance in the PC industry.

Verification testing of the DP-to-DVI and DP-to-HDMI cable adaptor types will follow the "DisplayPort Interoperability Guideline Adaptor Checklist" which is available for download at http://www.vesa.org/Standards/free.htm, under VESA DisplayPort Related Standards. It is recommended that developers of cable adaptors review the checklist to ensure display interoperability and to achieve VESA cable adaptor verification. The checklist verifies that the cable adaptor is implemented per the current VESA DisplayPort Interoperability Guideline, also available on the VESA web site.

VESA will offer the cable adaptor testing at a minimal fee and will offer verification logo licensing. Cable adaptors that pass the verification test will be listed on the www.displayport.org web site.

Verification testing for Source-side DP-to-DVI and DP-to-HDMI cable adaptors will become available in early 2010. Trial testing will take place at the DisplayPort PlugTest during December 7-10, 2009, in Yokohama, Japan.

Testing for DP-to-VGA adaptors, Sink-side adaptors, and other adaptor configurations will become available at a later date.
