My display is showing moving red dots/diagonal lines and squares that come and go on when playing some games. It only happens when I’m in a game playing and it only happens in dark areas. Works perfectly fine for everything else. Also my pc is connected through hdmi and I already tried switching them out. My tv has a refresh rate of 60hz and native 4K. Could it be because I play with vsync off and reach frames as high 120 FPS. Please help. What I’m talking about
