I have just installed Ubuntu 22.04 on a HP Probook 450 G9 laptop.

By default the highest option fo resolution that I get in Displays is 1366x768.

I tried to add manually another resolution with xrandr but the resulting image is of very poor quality. Here is what I am trying to do:

xrandr --newmode "1920x1080"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode eDP-1 1920x1080

And than I select the resolution.

I have a similar laptop, HP Probook 450 G8, the 1920x1080 option comes in by default, and the image is clear as it should be.

I have no problem setting the 1920x1080 resolution when I plug in an external 23 inch monitor.

I just realized that 1366x768 this is the maximum supported resolution by the laptop display:

Did not pay attention to this when buying the laptop.
