I would like to run my ultrawide monitor at 5120x2160 and 60Hz. Right now, I only get 30Hz.
My setup:
- I am running Linux (Ubuntu 18.04 LTS)
- The desktop is a Dell OptiPlex 7080, with DisplayPort 1.4
- The monitor is a Dell U4021QW (connected with the DisplayPort)
xrandr gives me only the 30 Hz option for 5120x2160:
I tried these instructions
cvt 5120 2160
xrandr --newmode "5120x2160_60.00" 949.00 5120 5536 6096 7072 2160 2163 2173 2237 -hsync +vsync
xrandr --addmode DP-1 5120x2160_60.00
xrandr --output DP-1 --mode 5120x2160_60.00
but I get the following error:
Anyone can help me with this issue?
Thanks!
