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.

    Yes, this isn’t new but it’s resurfacing thanks to the Steam Machine. Basically (off my memory), part of your title is accurate: AMD did create a FOSS driver with HDMI 2.1 which does not violate HDMI forum requirements, but the HDMI forum still vetoed it. I don’t know if it would necessarily “disclose the specification” as the first part of your title suggests, but I dig into the details enough to say for certain.

    Basically a dick move by HDMI. Maybe Valve can push their weight on this, we’ll see.
