Well, this is gonna sound incredibly stupid but I just found a fix for this, sort of, and 100% by accident. When I turn off my 2nd monitor, in the Nvidia control panel, instead of defaulting to the PC Resolution group of resolutions, at 1920x1080, it instead goes to Ultra HD 1080p which stops at 120hz.

That is what it defaults to. However, scroll down in that list and it gives me the usual resolution and refresh rate.

I feel very stupid right now. But yet again, I do not understand why this would even be a thing.

Not entirely certain if this is the correct place, but lately I've been noticing that if I hit Windows + P to disable output to my secondary monitor (ASUS PA238Q 60hz via DisplayPort)

Spoiler

(helps with focus for me sometimes + dark games are better this way cus no extra light for the eyes to adjust to) 

my primary monitor (144hz SAmsung C24FG73 via DisplayPort) will be limited to just 120hz. I get 144hz again if I turn the secondary monitor back on. 

 

I'm using a GTX970 with a mild overclock, but the issue was there before I overclocked. My other specs are on my profile if need be. Windows 10 64bit, fully updated.

Yes, but I can't go further than 120hz. Sure, the difference between 120 and 144 isn't a whole lot in my experience but I would like to get the full experience.
