Open Sourcing HDMI 2.1 Is An Open Sore For The HDMI Forum
Nvidia has historically been better at maintaining their open source driver, a perfect example being that it properly supports HDMI 2.1 on Linux with no extra fuss. Unfortunately that is not true of AMD’s open source driver, but that may well change soon. The HDMI Forum previously rejected a Linux driver for AMD + Mesa that added HDMI 2.1 support as it needed to be added to the driver as opposed to NVIDIA who have the logic inside their firmware. This led to most Linux users preferring DisplayPort, but there are times when HDMI is the best answer.
We now have good news, a submitted patch to the open source AMD display driver includes notes such as adding “HDMI FRL support to the amdgpu display driver” and that Display Stream Compression “is still being tested and will be sent out later”. It won’t be added immediately, but keep your eyes peeled for a new AMD driver with improved HDMI 2.1 support later this year.
