The external display's max. resolution is 2560 x 1440, but the maximum resolution I can select on the display settings is 2048 x 1152.

What can I do to use the display in its max. resolution?

System: elementary OS 0.4.1 Loki

Display driver: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

  • to get the max resolution the your output can reach use: xrandr -q this return to you the min and the max resolutions – Darleison Rodrigues Jun 14 '19 at 1:16

Based on answer you can use gtf height width refresh_rate and get an new modeline as response and then you can create new mode with the output of the first command xrandr --newmode modeline, after that you need to ensure in which output you want to set up the modeline, you can check this with xrandr -q after get the response add the newmode to the desired output xrandr --addmode OUTPUT "MODELINE" and apply the new modeline xrandr --output OUTPUT --mode MODELINE.

Please open terminal pressing Ctrl+Alt+T and execute xrandr -q to see the connected displays and their current resolution.
Then execute xrandr --output <monitor_name> --mode <resolution> to change resolution. For example, xrandr --output eDP-2-1 --mode 2560x1440

  • There's no 2560x1440 mode in xrandr output. Since I posted the issue I've tried all sorts of possible solutions, the closest one I got is 2560x1440 resolution at 30Hz 2560x1440 or 2560x1600 via HDMI which is not acceptable. I think it is my display driver that cannot handle the resolution. – Peter Apr 30 '19 at 18:10
