AMD released a new patch for Linux, RDNA 3 architecture GPU will support DisplayPort 2.0
The Video Electronics Standards Association (VESA) has launched the DisplayPort 2.0 standard in 2019, but so far there is no 8K resolution monitor with a DisplayPort 2.0 interface. According to the original plan, monitors supporting the DisplayPort 2.0 interface will be launched at the end of 2020, however, the global coronavirus pandemic has delayed engineers and hardware developers from discussing, fixing, and deciding the implementation of standards.
According to Phoronix reports, AMD has released a new Linux system graphics driver patch to prepare Radeon graphics cards to support DisplayPort 2.0 output. Since the RDNA 2 architecture graphics card does not support DisplayPort 2.0 output, the new patch should prepare for the new generation of RDNA 3 architecture graphics cards. Previously, VESA stated that it is currently developing displays that support DisplayPort 2.0 and will work with new chips. Related products will appear in the second half of this year.
DisplayPort 2.0 expands ultra-high bit rate support to 20 Gbit/s per channel, and the total of four channels can provide a rate of 80 Gbit/s, which is almost three times the current DisplayPort 1.4a and can support UHBR 10, UHBR 13.5, and UHBR 20 modes. Without compression, the DisplayPort 2.0 standard can support 10K@60Hz or two 4K@144Hz outputs, and higher resolutions can also be supported through DSC.
