Hi,
I tried to upgrade from Debian 9.12.. (for which the Dell monitor worked
well) to buster and got the above message. Also it says "Optimum resolution
1280 x 1024". I tried the howtoforge.com advice but without success.
At what point did this occur? What had you just done?
Does the machine boot at all?

Hello and thanks for your message.
Custom is for people to keep talking on-list, so that searching
can bring up problems and answers in the future.
I had used a step-by-step?? guide from nixCraft, the final step being to run
(as root) apt-full-upgrade to go from Debian 9.12 to Debian 10 Buster
I then did a reboot to verify that all was OK, and the above message came up
along with "Optimum Resolution 1280 x 1024 60 Hz".
The machine worked fine with this monitor for several weeks prior to this,
using Debian 9.12.
Yes the machine boots and allows me to do Ctrl-Alt-F1 etc. and login as user
and as root
That's good. The most likely issue is that the X server is
ignoring your monitor's capabilities (via EDID) and has just
picked a common resolution ... which is wrong for you.
You can fix this by adding some configuration:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Modes "1280x1024
Depth 24
EndSubSection
EndSection
The question is where to put this. /usr/share/X11/xorg.conf.d/
is a likely location. If the Identifier, Device or Monitor
strings are incorrect, you can find them in /var/log/Xorg.0.log
or in ~/.local/share/xorg/Xorg.0.log
