Feels like my 144Hz monitor is capped at 60Hz when watching a stream on my secondary monitor?

[Stator]

When I watch a stream, or even have a browser open on my second monitor, my games feel very laggy, sort of frame laggy I guess, but my FPS count is displaying my usual 250-300 (CSGO). I have tried lots of the solutions on here and none of them have helped me.

I play at 1280x960, 144Hz. This problem is only recent - it was fine about a month ago with the same resolution.

My second monitor is 60Hz, and it feels like my main display is getting capped at the refresh rate of my second monitor which to me seems very odd. Any help is appreciated.

Yep I've had this issue before, and the only way to fix is to run full screen on the main 144hz panel. Sucks but it's the only way I've figured out how to fix it.

I am really not used to native resolution on CS, so it was really hard for me to play on it. The guy above linked this, hope it helps you out also dude

Did you ever solve this issue? I had the same, but I believe I finally solved it now. My 144Hz monitor besides a 60Hz monitor also gave stutters and issues with many games. Sometimes I did not even have anything showing on my 60Hz screen except the desktop, and it would still lag on my 144Hz G-Sync. Games felt... "so so" for months until I figured out what to do. Now my GTX1070 pushes out more fps then ever. Mind you, I even had this problem when using my GTX1070 on my 144Hz and my other screen on my iGPU. It's a Windows issue, not nVidia. Using 2 desktops with different refreshes is just not handled correctly.
Many solutions were to set your primary screen to 120Hz or doing all of the things you've tried as well. None of them really fix it. What did fix it for me? Using nVidia Inspector!
There is a setting that's called: Multi-display/Mixed-GPU acceleration. Set this to "Single display performance mode".
Presto, after months and months I can now use my 60Hz screen to do whatever I want, without impacting the fps on my 144Hz screen G-synced. Finally!!
