dual monitor setup 144hz & 60 hz problem

Hello community,

 

I've set up a dual monitor setup. The main monitor is a 144hz one and the second is a 60hz one.

 

When I play a game in fullscreen on the main monitor, everything is working fine. I really do feel the smoothness of 144 fps. To check if i really get those 144 fps I enabled v-sync and it capped at 144, so everything is perfectly fine.

 

But:

 

As soon as I play a game in windowed or windowed-fullscreen mode and have something moving on the second monitor (Stream, video, bouncing smiles from chats) the game on the main monitor instantly looses its smoothness. When I test v-sync it caps at 60fps. This cenario also applies if on just move the windows task bar to the second monitor and play windowed / windowed-fullscreen.

 

So I'm stuck with this problem... either I

     -play fullscreen with 144hz but have to minimize the game all the time to browse something

     -or play windowed-fullscreen with 60hz

 

So my question is: why does my monitor lock at 60 hz as soon as i play windowed-fullscreen and have something moving on my second monitor?
