What is the hdmi 2.1 problem?

[–] davidgro@lemmy.world 4 points 1 month ago (1 children)

The licensing on HDMI doesn't allow open source implementations of at least some of the driver stuff.

So it works on Nvidia because of the closed source driver.

(I have not dug into details obviously)

and because of this, can't get 4k120 for my tv monitor which doesn't have displayport :( and similar size oled monitors are very expensive.

Wouldn't a DP - HDMI cable work?

(Don't know anything about this)

There's pretty much a single DP -> HDMI adapter that supports VRR by Cable Matters. Officially I don't think VRR should work over adapters, or at least other manufacturers don't invest the time to make it work.

Ah yeah ok was wondering why u wouldn't use DP instead. Couldn't an adapter work though?

[–] kusivittula@sopuli.xyz 1 points 1 month ago

adapter would work but i can only find one and it has bad reviews
