The Video Electronics Standards Association (VESA) officially presented the specification of the DisplayPort 2.0 interface. The new version of the standard means an increase in the maximum data transfer rate of up to 80 Gbps, which will allow displaying an image with 8K resolution, high refresh rate and high dynamic range (HDR) using only one cable and not using video compression.
In previous versions of DisplayPort coding 8b / 10b was used, thanks to which 20% of the interface bandwidth was "eaten" by given services. For example, from 32.4 Gb / s with DisplayPort 1.3 / 1.4 only 25.92 Gb / s remained in the image itself. In case of DisplayPort 2.0 a more efficient diagram 128b / 132b will be used, thanks to which 77.4 Gb / s will remain on the load.
On the physical level, the new interface adopted many things from Thunderbolt 3, which Intel made available to the public in March this year. In general, while the latter allows full duplex replacement at speeds up to 40 Gb / s, data is sent to DP 2.0 in one direction with a speed limit of up to 80 Gb / s.
If you're using a streaming display technology, DisplayPort 2.0 can be connected to a 15360 x 8460 pixel monitor or two 8K displays with a 120 Hz refresh rate. In this case, the extended dynamic range will be active in both cases. Without compression, you can use one 10K monitor (10,240 x 4,320 pixels) or a 144K 144K pair of monitors.
Like its predecessors, the DisplayPort 2.0 interface will be backward compatible and will use well-known physical connectors, including USB Type-C in an alternative DisplayPort mode. It is expected that the first devices servicing the new standard will appear on the market at the end of next year.
