New DisplayPort spec enables 16K video over USB-C



DisplayPort Alt Mode 2.0 is a brand new customary from the Video Electronics Requirements Affiliation that permits USB four to supply all of the bells and whistles of the DisplayPort customary in addition to transmitting USB knowledge. Meaning assist for 8K shows at 60Hz with HDR, 4K shows at 144Hz with HDR, and even 16Ok (15360×8460) shows at 60Hz with compression. It’s an enormous step in the direction of USB Sort-C changing into a real jack-of-all trades connector.

The USB four spec can already transmit DisplayPort knowledge, however AnandTech reports that the brand new customary remaps USB-C’s excessive velocity knowledge pins to unlock extra bandwidth for video. USB four is bidirectional, that means it might probably carry as much as 40Gbps of information in both path. Nevertheless, video doesn’t have to go each methods — you solely actually need knowledge to move out of your laptop computer to your monitor (for instance). This alt mode implies that all that bandwidth can be utilized to only ship video a method, that means you get a most uncooked bandwidth of as much as 80Gbps.

The alt mode additionally has different benefits. For instance, it implies that you don’t have to have a USB four controller at both finish of the cable, you may get away with simply DisplayPort {hardware} on the show finish. This could imply shows can afford to be barely easier, in keeping with AnandTech.

This can be a very simplified account of VESA’s Alt Mode announcement, and we’d totally suggest heading over to AnandTech in the event you’re after a deeper dive into the small print of the spec. VESA says that it expects the primary DisplayPort Alt Mode units to begin releasing subsequent 12 months. As is all the time the case with USB, nevertheless, you’ll should pay shut consideration to certifications and the small print of your units and cables to ensure they assist all the brand new options.
