Solved Extended monitor display refresh rate bug?

Specs: Windows 10, Intel 8700k, Corsair Vengeance DDR4 3200 2x8
I have two monitors, one at 120 Hz and another at 60 Hz. I run these on extended displays, and my 120 monitor uses G sync.

I haven't had this issue before, but recently, my 120 monitor would cut the refresh rate in half in any game (whether it be a game from Blizzard, Steam, U play, etc.) The in-game fps counter tells me 120 fps, but i know what 120 looks like and it's only doing 60. If i set the in-game fps cap to 60, then i get 30 fps. I can fix it by disabling my 60 Hz monitor mid-game and when i re-enable it mid-game, my 120 Hz monitor keeps its 120 fps.

I don't want to be disabling my monitor every time i play a game.
Before I noticed this problem I may have messed with Nvidia control panel settings and had a couple Ge Force driver updates, and a few Windows 10 updates, but I have no idea what would cause this problem.

My related specs are:
- Dell Gaming S2716DGR 27"
- ViewSonic VA2246M 22"
- Windows 10
- GTX 1080

✔ Best Answer

see step 7, sometimes the refreshrate of a monitor can reset to 59.94 hz or 60 after a crash or driver update.

best bet is to change it to 120 again.

however if you are still getting 60fps with Vsync on, then im clueless for now

I think it's just a bad idea to mix screens with different frequencies. You'll also notice that one screen looks "bad", that is if compared with the other screen. If this is for a corporate/production use, ok, but if this is your home setup, I would not go there.
