Video Electronics Standards Association, VESA, released version 2.0 of the DisplayPort video standard, which enables support for resolutions that go beyond…8K and higher refresh frequencies for 4K HDR and virtual reality applications.
DisplayPort 2.0 is the first major update of DisplayPort standard since March 2016: the new version offers up to 3 times the increase in bandwidth performance compared to the previous DisplayPort 1.4a, as well as new features to meet future requirements of the
Among the new features is the ability to overcome 8K resolutions, higher refresh frequencies and support for high dynamic range (HDR) at higher resolutions, as well as improved support for multiple display configurations, and thus greater flexibility, as well as a In addition to this, there is also greater energy efficiency.
The advantages of DisplayPort 2.0 can be exploited both through the native DP connector and USB Type-C connector, which carries the audio/video DP signal through Alt DisplayPort mode.
DisplayPort 2.0 is also retro-compatible with previous versions of the standard and incorporates all key features of DP 1.4a, including support for the Stream Compression (DSC) lossless Display with Forward Error Corre
The increased video bandwidth of DisplayPort 2.0 on the USB-C connector allows simultaneous transfer of high-speed USB data without compromising display performance. DP 2.0 uses the Thunderbolt 3 physical interface level while maintaining the flexibility of DisplayPort protocol, in order to increase the data bandwidth and promote convergence between the most popular I/O standards in the industry.
The previous version of DisplayPort, v1.4a, provided a maximum bandwidth of 32.4 Gbps, with each of the four lanes running at a connection speed of 8.1 Gbps/lane, with a maximum payload of DP 2.0 increases the maximum rate link to up to 20 Gbps/lane and offers a 128b/132b channel coding, more efficient, with a maximum payload of 77,37 Gbps, up to three times higher than DP
In practice, this means that DisplayPort 2.0 is the first standard to support 8K resolution (7680 x 4320) at a 60 Hz refresh rate with full-color resolution 4:4:4, including 30 bit per pixel (bpp)
The increased bandwidth of DP 2.0 also offers a high degree of versatility for different configurations. In addition to the above resolution of 8K at 60 Hz with HDR support, DisplayPort 2.0 allows a variety of high-performance configurations, of which VESA makes some examples (the above refer to the use with native DP connector or USB-C as
16K display (15360×8460) @60Hz and 30 bpp 4:4:4 HDR (with DSC)
A 10K display (10240×4320) @60Hz and 24 bpp 4:4:4 (no compression)
Two 8K displays (7680×4320) @120 Hz and 30 bpp 4:4:4 HDR (with DSC)
Two 4K displays (3840×2160) @144 Hz and 24 bpp 4:4:4 (no compression)
Three 10K displays (10240×4320) @60 Hz and 30 bpp 4:4:4 HDR (with DSC)
Three 4K displays (3840×2160) @90 Hz and 30 bpp 4:4: 4 HDR (no compression)
