If this was mine I know to not spend time on that.
My first 4k tv and I'm not really impressed bought a PS4 pro and the new tv just for RDR2 and well I've spent more time dialing in the picture than playing the game. in HDR mode the picture is very dim so I turned the brightness up and backlight up now I feel as if there is a haze. also, I have major juddering even with motion blur and judder reduction on max. I'm hoping to find solid "this is what you should set it to" guide. any advice would be much appreciated.
EDIT I just realized that the HDMI cable is 8 years old and not HDMI 2.0 could this be a factor.
