I wonder why only HDMI 2.0 on the Steam Machine, 'cos RDNA3 is capable of HDMI 2.1 and you need it to go over 4k 60Hz (I know it says 4k 120Hz for the Steam Machine’s HDMI but I suspect that’s either 4:2:2 color or DSC if it is really HDMI 2.0).
It’s the HDMI forum’s fault, they won’t allow amd to add HDMI 2.1 support to their Linux driver. It’s very possible that the hardware itself does support 2.1.

The HDMI Forum doesn’t allow opensource HDMI 2.1 drivers, AMD has the drivers ready but they aren’t allowed to release them. Yes, it’s that stupid
I think malicious is the correct word for it.
