Display does not work correctly

[HeinzDiedrichsen]

Initially everything was fine. Then came an update and now the display is milky and too large. I dont know what to do. What would be the proper BIOS Setting or how can the issue be settled?

That sounds unusual. Can you please attach a photo of the display when it is "milky and too large" ?

[Daniel van Vugt (vanvugt)]

Also, please run these commands and send the output:

  sudo apt install edid-decode
  for e in /sys/class/drm/*/edid ; do edid-decode $e ; done

Thank you Daniel,

I loaded Ubuntu again and now everything looks fine. Hopefully it will
stay this way.

With thanks to you
