USB 4 will be compatible with DisplayPort 2.0

The Association for Electronic and Video Standards (VESA), has announced that USB 4 will be compatible with the DisplayPort 2.0 standard, and will have support for resolutions greater than 8K.

VESA has announced the Alt Mode 2.0 specification, with which a USB Type-C connector can transmit data under the DisplayPort 2.0 standard at a speed of up to 80Gbps with all four cable lanes.

This new standard for video transmission was introduced in June 2019. It improved forecasting for future requirements and supports resolutions higher than 8K, high refresh rates and high dynamic range for high resolutions.

For example, it supports settings on a 16K (15,360 x 8,460) display at 60Hz and 30 4dpi 4: 4: 4 HDR with DSC or 10K (1.0240 x 4,320) at 60Hz and 24dB 4: 4: 4 without compression. Or two 8K (7,680 x 4,320) displays at 120Hz and 30 bpp 4: 4: 4 HDR with DSC, among others.

In March, USB-IF announced USB 4, the data transmission standard that will be backward compatible with USB 3.2, USB 2.0 and Thunderbolt 3 ports and devices. It will use two channels and support transfer rates of up to 40 Gbps, being compatible with USB Type-C cables, and will double bandwidth to simultaneously support multiple protocols.
