'DisplayPort 2.0' which supports 16K display and VR with maximum bandwidth 77.4Gbps is announced
by
The Video Electronics Standards Association (VESA), a standardization group for computer video peripherals, announced the first major DisplayPort update since March 2016 on June 26, 2019. DisplayPort 2.0 , a next-generation standard, will have a Disp data bandwidth of approximately 77.4 Gbps, approximately three times that of the previous version, and will be spread to 16K monitors and higher quality VR / AR devices that will be popular in the future Correspondence of is expected.

DisplayPort was introduced by VESA in 2006 as a new video output interface at the time of replacing analog to digital. At that time, HDMI appeared in digital home appliances such as TVs and HDD recorders, and even at the time of article creation, HDMI and DisplayPort were adopted in parallel as a video output standard for PCs.
As of June 2019, the latest version of DisplayPort, the payload of 1.4a (effective maximum) is 25.92 Gbps of 8.1 Gbps x 4 lanes. Although 1.4a supports up to 8K resolution and 60 Hz, 4K to 8K require display stream compression (DSC) depending on the refresh rate, and the resolution that is fully compatible even with no compression is up to 1440p.
DisplayPort 2.0 announced this time improves the maximum link rate to 20Gbps per lane, enabling more efficient 128b / 132b channel coding. The maximum payload is 77.37 Gbps, approximately three times the 1.4a. With this bandwidth, DisplayPort 2.0 is the first standard that can support '8K resolution with 60Hz refresh rate', 'full color 4: 4: 4 resolution' and '10 bit color HDR 10 media', VESA says .
VESA shows the following example as a display configuration that utilizes DisplayPort 2.0.
◆ Single display resolution
・ 16K display / 60Hz / 30bpp (bit per pixel) 4: 4: 4 HDR (with
・ 10K display / 60Hz / 24bpp 4: 4: 4 (without DSC)
◆ Dual display resolution
・ 2 8K displays / 120Hz / 30bpp 4: 4: 4 HDR (with DSC)
・ 2 4K displays / 144Hz / 24bpp 4: 4: 4 (without DSC)
◆ Resolution of triple display
・ Three 10K displays / 60Hz / 30bpp 4: 4: 4 HDR (with DSC)
・ Three 4K displays / 90Hz / 30bpp 4: 4: 4 HDR (without DSC)

In addition, when configuring a multi-display using 'DP Alt Mode on USB Type-C', which enables video output according to DisplayPort standard via USB Type-C connector, the following configuration is possible. .
・ Three 4K displays / 144Hz / 30bpp 4: 4: 4 HDR (with DSC)
・ 2 4K display (for VR · AR headset) / 122Hz / 30bpp 4: 4: 4 HDR (with DSC)
・ One 8K display / 30Hz / 30bpp 4: 4: 4 HDR (without DSC)

DisplayPort 2.0 is compatible with previous versions of DisplayPort. Furthermore, power efficiency is improved by the partial update function 'Panel Replay' that updates only the changed part of the video frame, and a small end device equipped with a high resolution display such as an all-in-one PC or a notebook PC. It is designed to optimize the power consumption and thermal performance of
VESA states that the first products incorporating DisplayPort 2.0 will appear by the end of 2020.
