Hello so in the nvidia control panel I get options to change hz, my monitor by default is gsync 144hz, but when I try to change the hz from the nvidia control panel to something lower like 120 or 100, no apply button will show up. I've tried switching the resolution and the apply button doesn't show up for that either. If I uncheck the ovveride game option or something like that, I get the apply button, so i switch the hz to 120 and I hit apply, it goes black screen and the option of 120hz goes back to being 144hz. Any help?
