DisplayPort 2.0 should be able to handle 4K 240Hz uncompressed!

AMD's next-generation GPUs may support 80Gbps DisplayPort 2.0 ports

Within AMD's latest open-source drivers (thanks @Kepler_L2), AMD has signalled that their next-generation Radeon RX 7000 series GPUs may be able to support DisplayPort 2.0, including the standard's maximum bandwidth of 80 Gbps. 

AMD's latest open source drivers reference UHBR20 (Ultra-High-Bit-Rate 20), which is a standard that is exclusive to DisplayPort 2.0. UHBR 20 signifies DisplayPort 2.0 support for up to 20 Gbps of bandwidth per lane, which over four lanes delivers a total of 80 Gbps of bandwidth. 

With DisplayPort 2.0, 4K 240Hz image outputs can be delivered in an uncompressed format without chroma subsampling or any other types of compression. At 8K, the standard can also support refresh rates of up to 85Hz without any issues, though 8K at 120Hz will require Display Stream Compression (DSC).

Within AMD's Linux patch notes, it looks like AMD is working on enabling UHBR 20 with DisplayPort 2.0. This will unlock the full potential of DisplayPort 2.0, which can offer 32 Gbps of additional bandwidth over what is available over HDMI 2.1 (48Gbps). With DisplayPort 2.0, VESA are enabling the creation of higher refresh rate 4K displays and high refresh rate 8K displays.

At the start of this month, VESA claimed that their first DisplayPort 2.0 source and sink devices had passed the organisation's certification process. That means that we should start seeing DipslayPort 2.0 devices come to market by the end of this year.

It is probable that this means that next-generation graphics cards will launch with support for DisplayPort 2.0, as DisplayPort 2.0 is expected to become a feature on many future enthusiast-class displays.
