VESA aggregates data, power interfaces into one connector

The Video Electronics Standards Association (VESA) has released DockPort, 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 also carrying high-resolution audio/video (A/V) data.

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

"As computing platforms become increasingly mobile, it becomes necessary to reduce the number of external connectors," explained Steve Belt, Corporate Vice President C Strategic Alliances & Solutions Enablement AMD, a VESA member company. "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."

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.
