HDMI Forum is unwilling to disclose the 2.1 specification for open-source (Linux): according to AMD, they had submitted a functional, HDMI 2.1-compatible driver [for linux?], which the Forum rejected. (www.heise.de)

There's always this option, could even include something like it in the box.

That's a passive cable and would require DP++. Funnily enough it would also require a HDMI 2.1 capable driver.

That probably won't work. It will get basic video and maybe audio through, but not features like VRR, which is why you'd care about HDMI 2.1 support at all
