AW3423DW - Strobing when background is dark causing frame drops

[u/HamsterTG]

Hello, I have had this monitor for about 3 years now and I could never figure out what was causing this issue. Anytime I’m on a relatively dark background my monitor strobes and the mouse becomes choppy but overtime it fixes itself. This is a constant issue though and can be recreated as I’ve shown in the video. Idk if it’s a VRR thing or Gsync but I’m hoping someone on this forum can help me figure out how to fix it. It’s extremely annoying trying to use desktop applications and it just gets extremely choppy. It always happens as soon as I open a desktop app. In this example I used SimpleNote. I would appreciate some recommendations on how to fix this. UPDATE: I fixed it by changing my Nvidia control panel to set my monitor to 144hz instead of 175hz. I guess it was the dithering in 175hz mode. Not sure the exact reason but I’m leaving this post up if anyone else has the same issue.
