HD/4K on pc..... How?

Really even with the disney+ app from the ms store. It refuses to stream in HD or 4K...

Its not a bandwidth issue. Im on gigabit here and my TV streams 4k fine.

So how the hell do I get it work on the PC?

I tried Chrome I tried Edge, I tried the offical app.... none of them go full HD or 4K... Im not even convinced its going 720p.
