Quick reminder on the likely reason why Valve's New Steam Machine only supports #HDMI 2.0:

""At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.""

This is what Alex Deucher, the maintainer of the amdgpu #kernel driver, said one and a half years ago here:

https://gitlab.freedesktop.org/drm/amd/-/issues/1417#note_2303163

And from the ticket it looks like the problem remains.

See also Alex's earlier comment from early 2021 in the ticket:

""HDMI 2.1 is not available on #Linux due to the HDMI Forum.""

@kernellogger Yeah, that’s a stupid situation … But … Is it really an issue? How is the average user affected by this?

@dirk @kernellogger As far as I know HDMI 2.1 enables 4K 120Hz and 8K 60Hz output, as well as variable refresh rate (VRR).

The first two may not be interesting for the Steam Machine, but the last one would be.

@Raqbit @kernellogger I wonder how many VRR televisions are out there.

@Raqbit @kernellogger @dirk there's plenty of VRR only monitors or people that need to use their HDMI port output as their external display. In fact the monitors at work are like this

@dirk @Raqbit @kernellogger @Lunaphied also VRR is actually becoming pretty widely available on TVs as most major game consoles including the Switch 2 include support
