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:

enter image description here

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!

    your GPU (Intel UHD 630) is not capable of that resolution. According to Intel's website, it can do max 4k @ 60Hz – Esther Jul 27 '22 at 19:50
  • @Esther I guess there is nothing I can do there? – GDG Jul 27 '22 at 20:07
  • put a (cheap) GPU capable of that resolution into your computer? otherwise doesn't look like it. – Esther Jul 27 '22 at 20:10

    If your system has a PCIe x16 slot, you could install a sufficiently powerful graphics card. Make sure it will actually fit in your system before purchasing it though - I made the mistake of not properly verifying the size of my GPU, and I had to literally use a pair of wire cutters on my desktop to cut off and bend enough pieces to force it to fit. (And the cover no longer goes on. :P) – ArrayBolt3 Jul 27 '22 at 20:10

  • Wondering if this may help https://dancharblog.wordpress.com/2020/08/18/5120x1440-49-ultrawide-on-intel-gpus/ It requires Windows, though... – GDG Jul 27 '22 at 21:09
