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:

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.

sudo get-edid | parse-edid
