I'm switching over to Ubuntu from windows 8.1. I've already managed to install nvidia's proprietary drivers but I'm stumped on how to set my overclock refresh rate for my korean monitor. On windows I had it set to 107 Hz and it worked flawlessly, but the nvidia control panel on Ubuntu seems to be limited to 60Hz. I've searched all over online for solutions, and nothing seems to work. It always says "refresh rate not supported by this resolution". I'm using the X-star 1440p korean monitor. Any help would be greatly appreciated!
Have you tried xrandr?
xrandr -r 107That works for me if it knows that the display will support it, although I have AMD. See below for more detailed information.
Yeah I've tried that several times. Nothing seems to work.
