One of the limitations of the AMDGPU Linux kernel graphics driver has been the lack of its support for HDMI 2.1 and later. AMD has wanted to support HDMI 2.1+ functionality under Linux but it’s been legally blocked by the HDMI Forum. But anxious independent users have been working on open-source patches for wiring up HDMI 2.1 into the AMDGPU driver outside of the realm of AMD and the HDMI Forum’s blessings. ……
Should I change to Displayport to unlock all my AMD GPU potential?
Yes.
Fuck the HDMI forum. Displayport is the one true connector
Need to pressure TV manufacturers to adopt it
What about USB?
Are you talking about USB4u2x2phaseCmk3v5?
Eh, I already moved to displayport and I’m not interested enough to go back
these patches certainly wouldn’t be accepted for upstreaming to the AMDGPU driver given HDMI Forum’s rejection already and needing to clear AMD’s legal review. It may help apply pressure on the HDMI Forum to change course especially if Valve and other stakeholders get involved, but this has been an unfortunate issue going back years already. AMD Linux users are best off just using DisplayPort where possible.
