Question Monitor flickering 4k 144Hz Freesync

[crisluni88]

Hi!

A few months ago I bought a 4k 144Hz Freesyn monitor (Gigabyte M32UC) and I've been experiencing some strange flickering while moving the camera around. This never happened with my previous monitor (Samsung 4k 60 Hz). Here are some videos to see this issue:

After some testing, I've got the following conclusions:

- More Hz, means that the effect is more visible.
- Higher values on the superresolution monitor setting (sharpening) make the effect more noticeable.
- When moving the view slowly the effect is more noticeable.
- There are games where it can be seen more easily than others (for example Resident Evil 4).

Does anybody know why this is happening? Is it related to this monitor or a feature in higher frame rate monitors?

Thank you!!

First off, that Google Drive link denied my access so if you could reevaluate on that please do. With that said, I've had this same issue with my 4K 60Hz GSync display only it was the opposite of your problem. I'm a really techy kind of person so with that said I actually managed to figure out the problem and that was the syncing between my GPU, the game & GSync. So, I found out a way to increase my Hz on the display without harming the panel and got it to 120Hz successfully without damage but that's just me. Back to you, it's probably what I said is your syncing between your GPU , the game and FreeSync instead. Have you ever tried disabling all possible syncing parameters & slowly enabling and disabling each one by one cuz that'll deduce the outcomes of why the flickering is happening or it's bad hardware lol............................food for thought.............................

Thank you for your reply! I fixed the link, could you please try and confirm that it's working?
What do you mean with syncing parameters? V-sync and frame rate are the ones that come into my mind. Is there any option on the nvidia control panel? I've got a RTX4090.

Thanks! 😊

The link worked and I've only seen that once from one of my friends who had that same issue only in a different way. It would happen only in Raytracing games where in specific areas, it would start creating what I called it "artifactual flickering" like you said where the GPU would render the scene but causes micro-major stuttering patterns only to find out that either disabling Raytracing or lower the resolution would help. Her and I are very close observers in the gaming fields. As for what I was talking about towards syncing parameters; NVCP has a variety of ways to sync your panel to the GPU and the game so there's probably a sundry of possibilities you could try. Also since you said FreeSync maybe even disabling that would help out as well as me noticing on your display that it says 160 OCed with DP. Maybe try doing a few experiments with using DP or disabling and enabling a few things in NVCP like Vsync or enabling someting called Fast which sometimes eliminates flickering or tearing......................................happy troubleshooting....................................

I tried a few things but nothing seems to make the issue disappear. I reduced the sharpening because this way is less noticeable but it's still there. It's quite annoying

Maybe it IS the sharpening!? I once saw the same kind of affect when I tried using NIS on my 2K 144Hz display and it caused it to do that exact same thing!! All I did was just turn it off or reset NVCP with DDU / reinstalled Windows to prevent it from happening again. It's a glitch where if your using a very high resolution and add additional sharpening to the image it'll flicker cuz of the fact that your probably using it too ingame. Plus you wouldn't need the extra sharpening when a better idea would be to use Clarity Filtering instead. Better feeling on your eyes and won't strain it too much. Food for thoughts after a bit...............................................
