VESA Issues Test Specifications for DisplayPort Cable Adaptors

The new test specification documents cover the popular Dual-Mode DisplayPort-to-HDMI and DisplayPort-to-DVI cable adaptors

The Video Electronics Standards Association (VESA) has issued new compliance test specifications for DisplayPort cable adaptors and those standards enable VESA members to have DisplayPort cable adaptors’ compliance tested through the association’s authorized test centers (ATC), or by completing the new self-testing and reporting option.

“The DisplayPort logo signifies that a product is based on next-generation display technology,” said Bill Lempesis, VESA’s executive director. “By simplifying the certification process for our member companies, we’ve given them easier access to the logo,” he said.

The new test specification documents cover the popular Dual-Mode DisplayPort-to-high-definition multimedia interface (HDMI) and DisplayPort-to-digital visual interface (DVI) cable adaptors, using either the standard DisplayPort or Mini DisplayPort connector, VESA says.

Compliance for active protocol converters such as DisplayPort-to-video graphics array (VGA) or DVI, and HDMI-to-DisplayPort, are also included, the association says. VESA members including Apple, BizLink, HP, Lenovo and, have completed the adaptor certification process and are shipping video adaptors to consumers, the organization adds.

“Being able to place the DisplayPort logo on our adaptors was extremely important,” said Ted Hsiao, BizLink’s vice president of product development. “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,” he says.

VESA’s third-party testing facilities have been selected to facilitate the certification process for international member companies. Authorized sites include:

  • Allion Test Labs in Beaverton, Ore.,
  • Cable Assemblies and Connector Labs ETC in Taoyuan Hsien, Taiwan, as well as a currently unnamed facility in Taipei, Taiwan
  • CESI Technology Company Ltd. in Beijing, as well as a currently unnamed facility in Shenzhen, China
  • Granite River Labs in Santa Clara, Calif.
  • Telecommunications Technology Association in Seohyeon-dong, Korea

“VESA requires very stringent testing before any product can use the DP logo,” said Quintin Anderson, Granite River Labs’ chief operating officer. “While the new CTS provides the self-test option, some vendors lack the proper test equipment to make this a viable option,” he said. Therefore, those who cannot perform self-testing, VESA’s ATCs serve as trusted advisors, working with the association’s members to get their products certified and secure access to the DisplayPort logo, he added.
