VESA's New Test Specifications Simplifies Certification of DisplayPort Legacy Cable Adaptors

Manufacturers of cable adaptor can now self-test their products to ensure its compliance with VESA test specifications. The new compliance test specifications (CTS (News - Alert)) for DisplayPort cable adaptors, announced by Video Electronics Standards Association (VESA), allows VESA members to test DisplayPort cable adaptors compliance through VESA's Authorized Test Centers (ATC) worldwide, or via the new self-testing and reporting option.

VESA members such as Apple, BizLink, HP, Lenovo (News - Alert) and StarTech.com have got their video adaptors certified and are shipping them to consumers.

According to a press release, the new CTS guidelines cover the Dual-Mode DisplayPort-to-HDMI and DisplayPort-to-DVI cable adaptors, using either the standard DisplayPort or Mini DisplayPort connector.

Compliance for active protocol converters such as DisplayPort-to-VGA or DVI and HDMI-to-DisplayPort are also included.

"Being able to place the DisplayPort logo on our adaptors was extremely important," said Ted Hsiao, vice president of product development at BizLink. "The logo is synonymous with high-performance and advanced display features. The new CTS enabled us to secure the logo for our cable adaptor products quickly, and differentiate our products from the competition."

In addition, VESA has selected third-party testing facilities to facilitate the certification process for member companies from around the world. Authorized sites include Allion Test Labs in Beaverton, Ore., Shenzhen, China and Taipei, Taiwan; Cable Assemblies and Connector Labs ETC in Taoyuan Hsien, Taiwan; CESI Technology Company Ltd. in Beijing; Granite River Labs in Santa Clara, Calif.; and Telecommunications Technology Association in Seohyeon-dong, Korea.

"VESA requires very stringent testing before any product can use the DP logo. While the new CTS provides the self-test option, some vendors lack the proper test equipment to make this a viable option," said Quintin Anderson, co-founder and COO at Granite River Labs. "For those that can't perform self-testing, VESA's ATCs, including labs like ours, serve as trusted advisors, working with the Association's members to get their products certified and secure access to the DisplayPort logo."
