I have tried factory resetting, and unplugging the tv along with all devices. I noticed the colors on my ps5 looked very bland compared to my roommates picture quality playing on an xbox one with an older vizio. Upon turning HDR off the color and brightness shot through the roof. The picture quality in general is much crisper as well and actually look like 4k with the HDR turned off. I have tried playing with the HDR settings on the Playstation and no matter what I do the colors, brightness and sharpness are miles below having it in SDR mode. Any ideas?
