DisplayPort 2.0 was originally announced in 2019 as “the new standard” and it should have been on the market for more than half a year now. However, following the promised HDMI 2.1 monitors, DisplayPort 2.0 screens were also delayed during the corona pandemic.
With DisplayPort 2.0, the new interface can transfer 20 Gbit/s of data on each lane. In total, that would mean that the data stream will top off at almost 80 Gbit/s. In short, that’s almost triple what DisplayPort 1.4a currently supports.
The higher bandwidth allows a single DisplayPort 2.0 connection to enable 10k resolutions at 60 hertz — or, say, two 4k displays at 144 hertz. Using the soon-to-be standardized DSC (
AMD’s current series of video cards, the RDNA2 generation, still uses DisplayPort 1.4 interfaces. On the 1.4 version of DisplayPort, a maximum of one 4k display can run at 144 hertz. Without stream compression, an 8k screen wouldn’t be able to perform above 60 hertz on this either.
In the near future, a few CDNA2 video cards will appear from AMD, although they are specifically aimed at data centers, where DisplayPort 2.0 would largely be redundant . AMD probably lays the foundation mainly to prepare DisplayPort 2.0 for RDNA3
