DisplayPort 2.0 is here!

77.34 Gbps of Bandwidth delivering 8K and Beyond

On June 27, 2019, VESA announced that it has released version 2.0 of the DisplayPort™ (DP) audio/video standard.

DP 2.0 provides up to a 3X increase in data bandwidth performance compared to the previous version of DisplayPort (DP 1.4a), as well as new capabilities to address the future performance requirements of traditional displays.

DP 2.0 Over USB Type-C

The advantages of DP 2.0 are enjoyed across both the native DP connector as well as the USB Type-C connector, which carries the DP audio/video signal through DisplayPort Alt Mode. DP 2.0 is backward compatible with previous versions of DisplayPort.  The increased video bandwidth performance of DP 2.0 carried over the USB-C connector enables simultaneous higher-speed USB data transfer without compromising display performance.

The new data rates of DP 2.0 come with a display stream data mapping protocol common to both single-stream transport and multi-stream transport, which facilitates multi-stream transport support of DP 2.0 devices for a single DP port on the source device to drive multiple displays either via a docking station or daisy-chainable displays.  First products incorporating DP 2.0 are projected to appear on the market by late 2020.

Below is the DP 2.0 Configuration Examples –

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)

When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as:

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