My ps4 works on any res apart from 1080p after i turned off deep colours. on 1080p the screen flickers between black, static, and the ps4 home screen. The screen also has red lines on it at 1080p. I know its a display issue because i managed to play a game through remote play. Is it my HDMI port and is there anything i can do to fix this issue?

Try a new/different HDMI cable and a different TV if that doesn’t work. That will eliminate the cable and TV as parts of the problem.
