Have you tried if this works with Debian buster? An easy way to do that is to download and boot one of the weekly generated Debian buster live images: https://www.debian.org/CD/live/ https://cdimage.debian.org/cdimage/weekly-live-builds/amd64/iso-hybrid/ https://www.debian.org/devel/debian-live/ Is the expected resolution available from the list of supported resolutions? If it isn't available, then probably the monitor hasn't exposed it in the EDID information. You can find this in the GNOME display settings, or by running 'xrandr' in a terminal. If it isn't available in xrandr, you can check the EDID information using the read-edid package. http://x.debian.net/howto/use-xrandr.html sudo get-edid | parse-edid -- bye, pabs https://wiki.debian.org/PaulWise
