Valve: HDMI Forum Continues to Block HDMI 2.1 for Linux
www.heise.de
Technically, the Steam Machine supports HDMI 2.1. However, Valve and AMD are not allowed to offer an open-source driver for it.

I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum’s decision that I am missing.

      I’m going to guess it would require kernel support, but certainly graphics card driver support. AMD and Intel not so difficult, just patch and recompile; NVIDIA’s binary blob ha ha fat chance. Stick it in a repo somewhere outside of the zone of copyright control, add it to your package manager, boom, done.

      I bet it’s not even much code. A struct or two that map the contents of the 2.1 handshake, and an extension to a switch statement that says what to do if it comes down the wire.

        nvidia has HDMI 2.1 last I checked.

        They can do it because their driver (even nvidia “open”) is a proprietary blob

        nouveau? Switch between drivers if you wanna use HDMI 2.1 or proprietary nvidia when you wanna game! It won’t make any sense, but it will piss off the right people :D

      It probably already has been, and Steam likely already has the specification. They just can’t open source an HDMI 2.1 implementation without consequences.
