Sites like rtings.com and tftcentral.co.uk have pretty decent measurement methodology. Probably best to stick to LG and Samsung but I can't say for certain.
I just replaced my old 48 inch C1 with this TV because of burn in. Was able to return it to Costco and get all the money back and put it towards this new one.
I have a 4090 and my display supports HDR and its disabled because fuck HDR. Do people actually like getting blasted with a floodlight because HDR automatically maxes your screen brightness? Like fuck I think my screen with HDR enabled is brighter than my lamp.
That's default behaviour on windows11, I have an MSI titan laptop that definitely supports it. I've done 0 to configure it. My brightness is typically at minimum or near to, enabling HDR immediately and consistently maxes brightness on the majority of the screen. It's utterly unusable. It goes with things that people say matters like 1000nits of brightness or whatever when I actually want like 300, so my eyes don't start bleeding.
That is default windows, if it's misconfigured then it ships misconfigured. I've done nothing except click the slider that turns it on, and then 5 seconds later off again as the dark mode settings menu blasts me with the full force of the screen.
If default doesn't work, I don't really feel like repeatedly blasting my eyes with full brightness until I figure out how to make it not burn out my retinas.
I think the issue is HDR requires the r part, being range, and I want it to not blast my eyes which anything above 20% brightness does if I'm inside, and default probably uses 100% of the brightness range and that actually causes pain.
Edit: to be clear, never made it to a game. Getting flash banged by the settings menu was bad enough thanks, don't need to deal with something intended to be a flashbang.
