I have a ps4 slim on my 4k hdr tv and some of the black colors and shadows in the games look grayish and dull and light reflections on people and objects look shaky and runny, any way to fix this in the tv menu? also in HDR do I chose 60hz+hdr, 60? or 30hz? i'm trying to get the best results for my games. in the ps4 settings sound and screen I was told to change the RGB to full but auto is recommended... can Ia change it to full? would that cause any damage to the console or TV?
