No, it's actually the opposite. He has an 8k monitor. Get rid of that, and then he has no blockers to using things the way he wants. Pretty simple solution.

If you buy hardware that is wildly incompatible with almost everything, then there's your problem. You don't buy things knowing it's incompatible, and then wait for compatibility to come around whilst complaining about it UNLESS you intend to buy it to put some effort into making it work on your own.

That's the entire point of this ecosystem and being able to upstream fixes.
