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.
