I have a 240hz monitor (asus pg279qm) and during any game I notice like a quick frame flicker like blinking and its really annoying to see it happen all the time and hard to record because its at random plus idk if my phone can capture it (I've tried and i can't tell). I tried looking online to see solutions but I can never get the right idea or can't find the problem I'm having and have only seen like 1 reddit post about the problem being recorded but no clear solution. I have tried different DisplayPort cords and it still happens. I've also saw from other posts that changing the refresh rate (Custom refresh rate) lower from 240hz in NCP can help but for me it doesn't save when I try setting it to 235hz or lower even though its supports 240hz????. I have g sync enabled on Fullscreen only and want it enabled but want a possible solution that isn't me just turning it off.
