[SOLVED] Multiple monitors - Different refresh rates = stuttering issue

[Domenix]

Allright. Hi my name is Domenix. I’ve tryed to solve my issue for about 2 years, but i give up each time i try cause there just doesn’t seem to be any way to solve it, however, the issue being a very ”simple” one 🧐.

Now i found this forum through linus tech tips and i hope you guys can help me !

issue: i have 3 monitors, 1x 240hz(gaming/primary)
2x 60hz (youtube/animation/editing)

whenever i play i game on my primary monitor (240hz) and i have something up on one of the 60hz monitors such as a youtube video or streamlabs overlays, the 240hz monitor lags as if it were synced down to match the 60hz monitor. I think this is a function of windows DWM to sync multiple monitors to same refresh rate if playing games on multiple monitors.

I will also add that the best help i’ve found is to join the Windows insider program to get the beta that fixes this, so i did that but this does not fix the issue after all.

i’ve tryed everything it feels like. I will put as much info down below as i can, but just ask if you need something else.

setup:
Lian Li der bauer edition
Intel core i9-10980XE
Asus rox strix z490-f
Asus strix rtx 3090
1000 watt power supply that i forgot the name of
Ballistix rgb ram 64gb
Cooling percists of nzx rgb system box with 9 fans sround the case

Got a few m.2 drives at around 1 terabyte each, dont know if it affects the issue but might aswell post it aswell

a gpu can not send out different refresh rates to different monitors as far as i know. it has to be synced up which is what you are seeing.

i turn off my secondary monitors when turning on a game to avoid this. mine will also sync with the 60 hz screen and as far as i can learn, it can't be helped.

That is actually not true what you are saying. Microsoft is claiming it's a dwm issue. Some people also have claimed that they got it to work through the insider program for windows. I however could not get it to work through windows insider which is why i need either help to how to get it to work through that or some other type of solution.

well if there is some beta feature only available to insiders and only working for a few of them, then perhaps that's the better place to ask how they got it working.

my guess is no one here is familiar with it so would have no way of helping you get it working.

i'd head to the insider forums and start looking for help there. i used to be an insider but gave it up a few years ago, when it became apparent ms was not concerned with what we had to say.
