DisplayPort 2.0 Supports Dual 4K VR Displays @120Hz

The Video Electronics Requirements Affiliation (VESA) has formally launched DisplayPort 2.zero, representing the primary main replace to the audio/video normal for the reason that entrance of DisplayPort 1.four again in March 2016.

DisplayPort 2.zero is alleged to supply as much as a three× improve in knowledge bandwidth efficiency in comparison with the earlier model. A number of the options embody assist for greater-than-8K resolutions on normal displays, greater refresh charges and excessive dynamic vary (HDR) assist at greater resolutions, improved assist for a number of show configurations, and assist for “4K-and-beyond” VR resolutions.

The affiliation maintains in a press assertion that some great benefits of DP 2.zero will probably be obtainable throughout each the native DP connector (backwards suitable) in addition to the USB Sort-C connector, which carries the DP audio/video sign via DisplayPort Alt Mode.

VESA mentions that via the DisplayPort Alt Mode, DP 2.zero has the power to supply knowledge transmission for two four,096 × four,096 VR/AR shows operating at 120Hz—30 bits per pixel (bpp) and four:four:four HDR with Show Steam Compression.

VESA says the primary merchandise incorporating DP 2.zero are projected to look available on the market by late 2020.

The VirtualLink connector, a VR normal created by a consortium of business gamers, was launched final yr, and consists of every thing you could join the subsequent technology of VR headsets to your GPU with a single, skinny cable—assist for 4 lanes of HBR3 DisplayPort for high-resolution shows, USB three.1 Gen2 (SuperSpeed USB 10Gbps) for headset cameras and sensors, and as much as 27 Watts of energy supply.

NVIDIA’s GeForce RTX playing cards embody hardware assist for the VirtualLink connector, though it’s but to turn out to be a common function on the most recent headsets at present obtainable, together with Valve Index, Oculus Rift S, and the HTC Vive Cosmos. Adapter dongles can be found, however we’ve but to see a VR headset that immediately makes use of the connector.

Since VirtualLink relies on DP 1.four, it’s doable we’ll hear a couple of commensurate ‘2.zero bump’ in capability quickly from the consortium themselves; you may hazard a guess at what a VirtualLink 2.zero might present from the DP 2.zero usecases said by VESA under:

USB-C connector through DP Alt Mode (two lanes):

Three 4K (3840×2160) shows @144Hz and 30 bpp four:four:four HDR (with DSC)
Two 4Kx4K (4096×4096) shows (for AR/VR headsets) @120Hz and 30 bpp four:four:four HDR (with DSC)
Three QHD (2560×1440) @120Hz and 24 bpp four:four:four (no compression)
One 8K (7680×4320) show @30Hz and 30 bpp four:four:four HDR (no compression)

Single show resolutions

One 16Ok (15360×8460) show @60Hz and 30 bpp four:four:four HDR (with DSC)
One 10Ok (10240×4320) show @60Hz and 24 bpp four:four:four (no compression)

Twin show resolutions

Two 8K (7680×4320) shows @120Hz and 30 bpp four:four:four HDR (with DSC)
Two 4K (3840×2160) shows @144Hz and 24 bpp four:four:four (no compression)

Triple show resolutions

Three 10Ok (10240×4320) shows @60Hz and 30 bpp four:four:four HDR (with DSC)
Three 4K (3840×2160) shows @90Hz and 30 bpp four:four:four HDR (no compression)
