Question

Not about VR, but a monitor resolution question that's really bugging me.

I have a 4k Samsung television that is capable of running 2k at 120 Hz and 4k @ 60 Hz. On my Nvidia control panel I have the resolution set to 4k @ 60Hz. Now for the question. If I leave the Nvidia control panel set at 4k 60Hz and just set the in games setting to 2k resolution, then will I still get the 2k@ 120 Hz, or will it be 2k @ 60Hz? Or do I also have to set the desktop resolution in the Nvidia control Panel to 2k@ 120Hz, while also settings the in the game settings to 2k @ 120Hz?
I hope this makes sense to someone and they can help with this :D

    Can't you just install fraps or a similar program and see the fps?



    I just need to know if it's running at 120Hz and a FPS program won't show me that, will it? When I game on a 60 Hz monitor it still shows well over 60 FPS.



    If you have vsync enabled and Fraps shows solid 120 (never above nor below) - then it's 120 Hz. If you don't activate vsync you could get Fraps to measure like 400 fps in some simple game - but you'll get no more than 60 of those shown with a 60 Hz screen - just remember to activate vsync (that will also provide best image quality with no screen tearing). 

    Btw, of course you could get 60 fps x 2 in 120 Hz (or 40 fps x 3 etc) if the game is demanding, so be sure to test using a game or app which your rig can achieve 120 fps - but with your 2080 Ti that should not be a problem :)

    Do I activate Vsync both in the Nvidia Control Panel and in the games settings?

    You can probably do both - but I think the Nvidia Control Panel setting overrules all in-game settings.
