Hello, im using a 144hz monitor as my main display and my old 60hz as a back up, i have an i7-9700k which i believed came overclocked at 4.57~ and a rtx 2060 super. I currently have my second monitor plugged into my cpu as i dont currently have an alternate cable and my card only has one hdmi slot. It has been working perfectly fine for a couple of weeks and was fine literally 2 hours ago but since shutting down my pc and coming back to it, when i open games now with my second monitor plugged in it causes it to crash and displays what i think might be stuck pixels showing green. Games still running normal on the single monitor. Does anyone know what may suddenly be causing this?
