on ubuntu 20.04 it wont let me set native resolution

Question

on ubuntu 20.04 it wont let me set native resolution I try to set the screen resolution to 1920x1080 (16:9) but the option doesn't show and the only option is 1024x768 (4:3)

Screenshot of display settings

This is what I get from xrandr

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
   1024x768      76.00*

This is what I get from sudo lshw -C video

  *-display UNCLAIMED

And I use an ASUS ROG with an RTX 2060 and my monitor is a DELL S2440Lb connected via HDMI

Please update your original question with some more information such as what is the make/model of your monitor? How is your monitor connected to the PC? Please post the full results of running xrandr in a terminal. — codlord, Jul 13 '21 at 13:51
Please [edit] your question and add the output of lshw -C video. — Kulfy, Jul 13 '21 at 14:16

Sometimes your monitor settings just aren't detected properly and you need to set a custom modeline. This might be of use https://ubuntuhandbook.org/index.php/2017/04/custom-screen-resolution-ubuntu-desktop/ — sleepyeyesvince, Jul 13 '21 at 15:01
