The Video Electronics Standards Association VESA has announced the release of version 2.0 of the DisplayPort Alternate Mode (Alt Mode) standard. This version provides compatibility with published by USB-IF and provides all the features of the latest version of the DisplayPort 2.0 standard through the USB-C connector.
Recall: DisplayPort Alt Mode allows using a conventional USB-C connector to transfer audio / video data at speeds typical of the DisplayPort interface, as well as provide data transfer via USB and power up to 100 W through a single cable.
In DisplayPort Alt Mode 2.0, the USB-C connector can transfer up to 80 Gbps of DisplayPort video data using all four high-speed lanes of the cable, or up to 40 Gbps while transferring data from SuperSpeed USB. VESA expects the first products that support DisplayPort Alt Mode 2.0 to hit the market in 2021.
DisplayPort 2.0 was - The standard provided a threefold increase in data bandwidth compared to the previous version of DisplayPort, and also brought new features to meet future display performance requirements. We are talking about support for 8K, and higher refresh rates, and high dynamic range (HDR) at higher resolutions, and so on.
USB-C is becoming the connection of choice in laptops and mobile devices, and thanks to DisplayPort Alt Mode 2.0, gaming monitors, professional HDR displays, AR and VR headsets can be connected through this connector at speeds up to 80Gbps along with data transfer and power.
"The updated VESA DisplayPort Alt Mode specification includes a number of related developments, including innovations in the interface discovery and configuration process, and power management, all to provide full integration with USB4," said Craig Wiley, VESA board member and leader of the DisplayPort Alt Mode subgroup. "This major improvement to the standard has been in development for several years and was only made possible through the combined efforts of VESA and USB-IF."
