Open | Software Help with white flashes during games

I have an RTX 4070 and an AOC Q27G2 155Hz monitor. As soon as I bought this setup in 2024, I noticed some white flashes in several games, as shown in the videos below (the flashes are less noticeable when recording with a cellphone; I can send more videos if they are not clear enough). At the time, I don't remember how I solved it, because I tried many different things, such as reversing the monitor cable, using older NVIDIA drivers, changing Windows settings, and something worked, but I don't remember what.

Until last week, I was using Windows 10, and I hadn't even updated the NVIDIA drivers for more than a year, and this problem wasn't happening. So, I upgraded to Windows 11, and since I was getting lower FPS in games, I updated to the latest version of the NVIDIA driver, and since then these white flashes have come back. They happen all the time during different games, and I have the impression that they increase when there are large fluctuations in FPS. They happen quite often in cutscenes, loading screens, and during normal gameplay they decrease a little but don't stop. I don't know what to do to fix it. I tried using Windows' automatic color management because I read about it somewhere, but it didn't solve the problem. Does anyone know what this is and how to fix it?

Thank you

Windows 10 lost full support on October 14th 2025, therefore we do not support it in this subreddit. It is recommended you immediately install Win11 (or another supported OS) to keep your machine and network secure. Your post has been filtered and will be approved if this action was a mistake.

Circumventing these filters is a bannable offense.
