The Video Electronics Standards Association (VESA) has introduced the successor to DisplayPort 1.4a. DP 2.0 improves upon its predecessor with a 3X increase in bandwidth, allowing resolutions greater than 8K. The update also enables higher refresh rates, HDR support at higher resolutions, and 4K-and-beyond VR resolutions.

Single display resolutions
  • One 16K (15360×8460) display @60Hz and 30 bpp 4:4:4 HDR (with DSC)
  • One 10K (10240×4320) display @60Hz and 24 bpp 4:4:4 (no compression)
Dual display resolutions
  • Two 8K (7680×4320) displays @120Hz and 30 bpp 4:4:4 HDR (with DSC)
  • Two 4K (3840×2160) displays @144Hz and 24 bpp 4:4:4 (no compression)
Triple display resolutions
  • Three 10K (10240×4320) displays @60Hz and 30 bpp 4:4:4 HDR (with DSC)
  • Three 4K (3840×2160) displays @90Hz and 30 bpp 4:4:4 HDR (no compression)
The previous version of DisplayPort, v1.4a, provided a maximum link bandwidth of 32.4 Gbps, with each of the four lanes running at a link rate of 8.1 Gbps/lane. With 8b/10b channel coding, that equates to a maximum payload of 25.92 Gbps. DP 2.0 increases the maximum link rate to up to 20 Gbps/lane and features more efficient 128b/132b channel coding, delivering a maximum payload of 77.37 Gbps – up to a three-fold increase compared to DP 1.4a. This means that DP 2.0 is the first standard to support 8K resolution (7680 x 4320) at 60 Hz refresh rate with full-color 4:4:4 resolution, including with 30 bits per pixel (bpp) for HDR-10 support.
 
That's great news. The sooner the better that manufacturers start adopting this. Those are some awesome specs. I admit that HDMI 2.1 looks impressive but this is even better. Since DP1.4/HDMI 2.0 I've been seeing high resolutions plus all the bells and whistles of color depths combined with higher hz saturate pretty easily. This should give us some time till the next big thing come out.
 
I wish the industry could either decide on either DP or HDMI, or make sure that all displays and cards supported both formats.

One standard is proprietary and one is open source iirc and there are industry leaders sitting on the boards of both standard's organizations. Unlikely we'll get only one connection any time soon.
 
I'm not sure they can claim 4:4:4 and being visually lossless when using DSC.
DSC has a maximum of 4:2:2.
16bit/colour is impressive but its a shame they dont have a version that can keep 4:4:4 intact.
If converting to 4:2:2 or 4:2:0 is their only method of compression, surely its better to send that instead?
There is no suggestion of any other compression which makes DSC look redundant.

edit
It does indeed look suspect.
By being visually lossless, a typical observer of a display, under typical viewing conditions, would in most cases not notice any difference or degradation of images or video after compression, when compared with the uncompressed image or video.

It is straight forward conversion to 4:2:2 or 4:2:0 and they hope nobody can tell the difference!
