VESA unveils the biggest update of its DisplayPort PC display standard since it was first ratified in 2007. The new DisplayPort 2.0 specification, which is expected to arrive on monitors by the end of 2020, including bandwidth support for 8K screens and much more. This new bandwidth, with a maximum speed of 80 Gbps, is almost three times as much as in the previous DisplayPort 1.4 specification, and it means that you can run a gaming monitor at 4K / 144Hz with HDR support, or two 8K dispaly at 120Hz with HDR. This is what VESA aims for the future:
Some screen resolutions:
One 16K (15360×8460) screen at 60Hz and 30 bpp 4: 4: 4 HDR (with DSC)
One 10K (10240×4320) screen at 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 screen 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 new standard comes just the moment we go beyond 4K monitors. Apple recently announced its own 6K screen and Dell has already supplied an 8K monitor. DisplayPort 2.0 now naturally goes against the HDMI 2.1 specification, which will be prepared in the future for the same higher resolution monitors, in addition to wider color ranges and improved refresh rates.
VESA supplies its own standard via the DisplayPort connector or via USB-C. The company also incorporates Intel's Thunderbolt 3 technology, thanks to the fact that Intel makes it royalty-free. Although this increases bandwidth, it also introduces some of the cabling issues we have seen with Thunderbolt 3 before.
Anandtech reports that VESA did not really hear the cabling riddle. Thunderbolt 3 requires active cabling for high bandwidth unless it is really a short run, and that means a more expensive cable with transceivers at each end. However, since DisplayPort 2.0 is based on Thunderbolt 3, it should be much easier for companies to create and test products. VESA now expects the first products with DisplayPort 2.0 to arrive at the end of next year.
