Does it have DisplayPort connection? HDMI is a mess in general. Avoid it if possible.

since hdmi 2.1 just came out for amd with the 6000 series, it may not be entirely supported yet in the kernel amdgpu driver. if your monitor has a displayport then that would be the best to use. if not, then unfortunately it might not work.

i've tried googling myself to find any info about hdmi 2.1 working on amdgpu with linux but i haven't been able to find anything outside support is coming. i personally don't have a hdmi 2.1 monitor so unfortunately i can't test myself.

Nothing more to say. Display port is not option unfortunately.

that is extremely disappointing on hdmi's part. i don't understand the reason for wanting to keep it closed up.

They simply don't understand the approach of open standards. HDMI is directed by a corrupt cartel with the only purpose of fleecing hardware manufacturers with patent fees. If not for their stranglehold on the TV market, HDMI would have been dead a long time ago and you'd see DisplayPort used everywhere today.

HDMI needs to go the way of the doo doo . Why the big manufactures didn't decided this long ago is beyond me.

Corruption. It's controlled by cartel that profits from patent fees on it. They dominate TV market and that's why HDMI didn't disappear yet.

I don’t think you’ve posted that same link enough times yet.

Commercial entities would see no value in an open standard. Quite the contrary, in fact. If they’re paying for something, it means the seller takes responsibility for it and that mitigates risk. Since they’re making money, they are happy to spend money.

Open/royalty free standards are only of value to people who put in work for free and give away their work for free. That’s a tiny bubble in the sea of commerce and insignificant to the tune of less than 1% I’d say.
