DisplayPort 2.0: Ready for 10 Bit 8K 4:4:4 with 60 Hz

bild Last week, the Video Electronics Standards Association (VESA) introduced a new DisplayPort generation with version number 2.0. Compared to the current standard (1.4a), the interface for the transmission of monitor signals is expected to make an enormous leap. The data rate should triple (from 25.92 Gbit/s to 77.37 Gbit/s), which will be sufficient for 8K reproduction with 60 Hz at 10 Bit 4:4:4 color depth.

DisplayPort 2.0 will (like USB 4.0) be based on Thunderbolt 3. Since Intel and Apple released this standard at the beginning of the year, other manufacturers will also offer corresponding solutions. Nevertheless, all features of DisplayPort 1.4a will continue to be supported.

The integrated compression technology that was christened Display Stream Compression (DSC) is likely to be exciting. HIermit should enable much higher data rates, like 16K (15360x8640) with 60Hz and 10 Bit 4:4:4. The quality is called "visually lossless".

This sounds exaggerated for a monitor, but several monitors can also be serially connected via a DisplayPort output using the multi-stream protocol. In such a case, two 8K/60Hz or four 4K/120Hz displays can be controlled via a single DisplayPort 2.0 output using DSC.

The first devices can be expected at the end of 2020.
