I have my desktop plugged into an OLED tv right now it runs fine and looks good. Do you mean HDR specifically? HDR doesnt work but it does seem like there’s finally movement in that space with valve and others pushing for support. I think last news I heard about it was this thing.

So if you want to know if there would be a problem with an OLED screen and true blacks and all that then rest assured you’re good, but HDR will not work and probably wont in the near future.

That said while you’re searching around I suggest searching the model thoroughly before pulling the trigger on the buy. Laptops have a lot of esoteric hardware and acpi which means even if the big pieces should be fully compatible it might not be. Also Ive heard good things about framework but dont own one.
