New DisplayPort Cable Adapter Certification Program

displayportThe Video Electronics Standards Associate (VESA) recently introduced a new certification testing and DisplayPort Certified Logo for Dual-mode DisplayPort cable adaptors. These dual-mode cable adaptors allow for seamless interoperability between a Dual-mode DisplayPort PC or graphics card and a DVI monitor or HDMI TV. The certification program was designed to help customers identify cable adaptors that have been thoroughly tested and certified for proper functionality with other DisplayPort products through the use of a distinctive logo and product packaging.

The DisplayPort standard, developed as a replacement for digital (DVI) and analog component video (VGA) connectors, uses simple adaptors to provide interoperability with DVI, HDMI and VGA displays.  When plugged into a Dual-mode DisplayPort PC or graphics card, these adaptors can output either Single Link DVI or HDMI signaling. Almost all DisplayPort PCs with integrated graphics or discrete Graphics Processing Units (GPUs) have Dual-mode DisplayPort capabilities.

Dual-mode DisplayPort cable adaptor certification and testing follow the DisplayPort Interoperability Guideline Adaptor Checklist. The checklist was designed to help developers ensure display interoperability and achieve adapter certification. Allion Testing Labs in Taiwan is certified to offer Dual-mode DisplayPort adapter certification testing for both VESA members and non-members for a nominal fee. Once a product passes certification testing, a logo license agreement is available through VESA at no cost for VESA member companies and for $1500 USD for non-members.

For engineers, this certification program represents a new opportunity to distinguish your product. Thorough testing and validation, such as industry standard certification, helps ensure product quality; this can save manufacturers from the high cost and headache of managing customer complaints and merchandise returns. And by choosing a certified testing lab with full engineering support and services, developers can produce the highest quality product while significantly reducing cost and time-to-market.
