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.

    HDMI has never been an open standard (to the best of my understanding anyway). You’ve always needed to be an adopter or a member of HDMI forum to get the latest (or future) specs. So it’s not like they’ve just rejected a new idea.

    Okay not publishing the spec is still the same, but something else is new nonetheless.

    AMD is an adopter*, they have the spec and they implemented a driver for 2.1 intended to be open sourced in Linux. But they were still blocked from publishing it. For HDMI 1.4 that wasn’t an issue yet from what I’ve found (though it’s always hard to search for non-existence). Open source implementations of HDMI 1.4, even in hardware description languages, seem to exist.
