DisplayPort Alt Mode 2.0 for Type-C devices allows for 16K display resolutions

The Video Electronics Standards Association has released a new specification that opens the door for future USB-C devices to support DisplayPort 2.0 and ultra-high resolution displays.


DisplayPort Alt Mode 2.0 brings a number of upgrades to the USB4 protocol.

Originally announced in June 2019, DisplayPort 2.0 supports resolutions up to 16K, higher refresh rates, HDR support at higher resolutions, and improvements in multi-screen and screen support. augmented and virtual reality. On Wednesday, VESA released the specification for DisplayPort Alt Mode 2.0, which will allow future USB4 and USB Type-C to take full advantage of these improvements.

“The updated VESA Alt DisplayPort specification includes a number of under-the-hood developments, including interface discovery and configuration updates as well as power management, to ensure seamless integration with the USB4 specification, ”said Craig Wiley, VESA Board member and Leader of the DisplayPort Alt Mode subgroup.

DisplayPort Alt Mode 2.0 now allows USB Type C devices to provide single connector docking solutions for a range of devices with 80 Gbps video bandwidth and other enhancements introduced with DisplayPort 2.0.

USB4, which Apple will likely adopt in future Mac devices, is a convergence of the Thunderbolt and USB protocols. Upon release, it is expected to offer royalty-free Thunderbolt, which could pave the way for more and cheaper Thunderbolt accessories to hit the market.

The first of the USB4 devices is expected to arrive in late 2020. VESA has said it expects the initial deployment of DisplayPort Alt Mode 2.0 to occur sometime in 2021.
