Interface extension adds USB, power charging capabilities

The Video Electronics Standards Association (VESA) unveiled the DockPort standard, an optional extension of the DisplayPort standard that will allow USB 3.1 data and DC power for battery charging to be carried over a single DisplayPort connector and cable that also carries high-resolution audio/video (A/V) data.

Developed by several VESA member companies , this new extension of the DisplayPort standard is fully backward compatible with all existing DisplayPort devices. When a DockPort-enabled DisplayPort source—such as a computer or tablet—is connected with a DockPort-enabled DisplayPort sink—such as a display monitor or docking station—A/V plus USB data and power will be transferred over a common cable through a single connector. If either the source or sink device is not a DockPort-enabled, then source and sink will recognise only the DisplayPort A/V data stream.

"With DockPort, VESA has developed a technology standard that enhances elegant docking designs, reduces mobile form factors, and enriches the user experience with streamlined, one-cable access to a wide range of external displays, peripherals, and storage," explained Steve Belt, corporate VP—Strategic Alliances & Solutions Enablement AMD, a VESA member company.

DockPort is the first royalty-free industry standard that combines these three essential interface functions into a single connector. VESA first revealed its intention to develop this standard at the 2014 International Consumer Electrics Show. It anticipates that several vendors will demonstrate DockPort-enabled DisplayPort systems at Computex Taiwan, which begins today.

VESA is developing a compliance test protocol to certify systems that meet the DockPort standard. Systems that satisfy this test protocol will be permitted to display VESA's new DockPort logo on their packaging as a guide for consumers seeking this capability.

The DockPort standard is offered to VESA members without any licence fee.
