I can't get my monitor to set the refresh to 120hz. I'm using an nvidia gtx 970. The outputs are below (I'm using a 120 hz monitor & I was able to set it to 120hz in Ubuntu 15.04 when using an AMD graphics card). Now I am using Ubuntu 14.x and it won't let me set it to 120 hz. Please advise.

$ xrandr

Just read about someone else having a similar issue and saw they were doing nvidia settings using 

sudo nvidia-settings

I change it on that menu and it worked. How come xrandr doesn't work?

  • Is this monitor using DUAL DVI links? Because if not, then the nvidia app must be lieing to you since a single dvi cable can't handle that refresh rate at that resolution. – psusi Jun 15 '15 at 0:43
