DisplayPort

It is a high-definition digital display interface standard that can be connected to computers and monitors, as well as computers and home theaters. In terms of performance, DisplayPort 2.0 supports a maximum transmission bandwidth of 80Gb/S. On June 26, 2019, the VESA standard organization officially announced the new DisplayPort 2.0 data transmission standard specification, which is closely integrated with Thunderbolt 3 and USB-C to meet the needs of 8K and higher display output requirements. This is the first major update since the DisplayPort 1.4 protocol.

Before that, the theoretical total bandwidths of DP 1.1, 1.2, 1.3/1.4 were 10.8Gbps, 21.6Gbps, and 32.4Gbps, respectively, but the efficiency was only 80% (8/10b encoding), which was difficult to meet 6K, 8K high resolution and High color depth and high refresh rate requirements.

DP 2.0 increases the theoretical bandwidth to 80Gbps in one fell swoop, and adopts a new encoding mechanism 128/132b, which increases the efficiency to 97%, and the actual usable up to 77.4Gbps, which is equivalent to three times that of DP 1.3/1.4, far exceeding HDMI 2.1 The theoretical bandwidth is 48Gbps.

In this way, DP 2.0 can easily support 8K/60Hz HDR, >8K/60Hz SDR, 4K/144Hz HDR, 2×5K/60Hz and other output formats, not only can support any 8K display without compression, but also can support up to 30 -bit color depth (more than 1 billion colors), achieve 8K HDR.
