Brehs, set RBG Range to LIMITED for the LG CX in PS5 settings. The image looks a lot better. I set it to automatic in the past based off recommendations and it seems the PS5 set the RBG range to full. Full looks a lot worse compared to limited.
Here are the settings I recommended in the past and people can vouch for making their games look better than the factory settings
Game Mode
OLED Light - 92
Contrast - 85
Brightness - 46
Sharpness - 20 (0 was too soft, bumped it to this based off a random recommendation on reddit, looks good)
Color - 57 (can bump up to 65 for more vibrant image, beyond this it gets oversaturated IMO)
Tint - 0
Color Temperature - Warm1
Dynamic Tone Mapping set to on
Black Levels set to low
Things like MPEG noise reduction ,motion control, image soothing true motion, eye care, and anything else related to video watching should be set to off and will be set to off out of the box anyway I think so leave everything else alone
For OLED light, use whatever feels comfortable on your eyes but continue to use the rest of my settings. I'm still experimenting w/ sharpness but 20 seems to be the sweet spot for now
