im using a 3080 ti on a sony KD65X85J 65" 4k 120hz tv. the nvidia control panel only gives the option for 4k 60hz hd, or if i go to the pc section, it shows 3940 x 2160 120hz, but on the pc setting, everything is blurry, even with dsr at 4x. i have an 8k rated hdmi cable that is 5-6 feet long on the 4th hdmi port on my tv that specifies 4x 120hz. i dont know how to fix it so i have 4k HD 120hz. does anyone know how to fix this?
