It's annoying when Windows, Linux, Android, and MacOS will let you play any resolution video you like even when it's above your native resolution.

I bet it affects many people with HDR monitors that aren't 4K, there's tons of those.

A good percentage of users that hook up Roku to a PC monitor will run into this.

Roku only supports HDR at 4K and normally I can just set youtube or whatever to "4K HDR" and OS downscales. Roku won't do it.
