Video Electronics Standardization Association VESA has announced the release of a new version of the DisplayPort Alt Mode 2.0 standard for video transmission. Its key feature is compatibility with the USB4 specification - due to its high bandwidth, a new type of cable will provide 8K @ 60 Hz image transmission and simultaneously supply power to connected devices.
Back in June 2019, the DisplayPort standard was updated to version 2.0 with support for 8K monitors. The main difference between Alt Mode and the basic specification is the connection scheme of external devices. Using all four high-speed lines, the standard provides a bandwidth of up to 80 Gbps of video data per second, or up to 40 Gbps while using SuperSpeed USB.
With the advent of DisplayPort Alt Mode 2.0, not only monitors, including professional models with HDR support but also devices such as VR helmets can be connected to a PC through one universal connector. At the same time, they will not need an additional power wire with a power of up to 100 W - its role will be played by a universal cable in parallel with image transmission.
The appearance of the first commercial devices supporting DisplayPort Alt Mode 2.0 is expected in the market in 2021.
