VR rivals come together to develop a single-cable spec for VR headsets
Future generations of virtual reality headsets for PCs could use a single USB Type-C cable for both power and data. That's thanks to a new standardized spec from the VirtualLink Consortium, a group made up of GPU vendors AMD and Nvidia and virtual reality rivals Valve, Microsoft, and Facebook-owned Oculus.
The spec uses the USB Type-C connector's "Alternate Mode" capability to implement different data protocols—such as Thunderbolt 3 data or DisplayPort and HDMI video—over the increasingly common cables, combined with Type-C's support for power delivery. The new headset spec combines four lanes of HBR3 ("high bitrate 3") DisplayPort video (for a total of 32.4 gigabits per second of video data), along with a USB 3.1 generation 2 (10 gigabit per second) data channel for sensors and on-headset cameras, along with 27W of electrical power.
That much video data is sufficient for two 3840×2160 streams at 60 frames per second, or even higher frame rates if Display Stream Compression is also used. Drop the resolution to 2560×1440, and two uncompressed 120 frame per second streams would be possible.
Framerate is too low, and it's not wireless. Lame.
