I’m having a lot of troubles with this, i can set a 144 refresh rate in nvidia-settings, and save the configuration into /etc/X11/xorg.conf but when i restart the resolution and framerate goes “auto (1920x1080x60)” again.
Set the refresh rate from “Display” utility of OS like Display in Unity and gnome-display-property in GNOme . Save changes there and I think that settings will be persistent also after X start.
I have a LC32JG Samsung, it says 144hz in the screen options but i can’t unstuck my computer from 60hz, going in the nvidia panel i found that i can try out custom values, there i forced it to 144hz, endless loop of connection to the DP, screen can’t read? 1060gtx. So wtf is the screen subdividing the shit out to 144hz or something ? Even so it should be fine with 144hz input :/…
I had the same issue until I figured out the trick… Set the resolution and refresh rate in Nvidia Settings. Save that then open your system’s Display Settings (In Mint, which I’m using it’s the one in System Settings / Hardware / Display. Hit the “Apply” button.
