It says on my LG tv it says that it does not suppourt HDR.
Are there cables you can buy that could enable HDR on my television or do I have to get an entirely new TV?
I assume you may be referring to getting HDR to work in RE4 Remake? It was the other way around for me, I assumed since my new TV DOES support HDR, I would be able to just turn it on in game. Nope, it will just say you need an HDR capable display.
Then after doing a net search I found you need to enable HDR in Windows (I play on PC). I'm not sure whether in your case you need to enable HDR in the PS5 OS or not, but I DO know the display itself has to support it for it to work.
HDR looks awesome in RE4R, but unfortunately I cannot get Nvidia's ShadowPlay capture tool to capture it well. It will capture instead a very washed out looking clip. The captures actually look far better without HDR on. Nvidia have mentioned HDR problems needing to be sorted out with MS and game developers in their latest driver notes, but these HDR woes have been going on for YEARS.
I would think consoles might have less of a problem getting HDR to work properly, because it's not a 3 headed monster like MS, Nvidia, and game devs. It's mainly between AMD and the game devs.
BTW, a bit of a warning with LG Smart TVs. BEFORE you connect them to the net, especially just after registering one on their site, go to Settings>Support>Privacy & Terms on the TV, and enable the bottom option, which makes them have to cease selling your personal info. Otherwise you can get apps popping up, even while you're gaming, asking if you want them to play music, or whatever they do.
