I'm using windows 10 and a BenQxl2411z monitor. I was trying to change my refresh to 120 from 144 so I could use blur reduction and make my screen brighter, but it won't seem to work. I have tried doing it through display adapter properties in windows, and also in the nvidia control panel. The confirm window shows up after I change it and then the nvidia control panel window flashes and it reverts back to 144 even if I click confirm. I'm not really sure why it doesn't want to change, I don't ever remember having this problem before and I'm wondering if it has anything to do with me having 2 monitors? It probably doesn't but just in case I'm using 2 monitors and the other one is an Asus VG245 set to 75hz.
