Tod,

You're becoming like Karl...perhaps you shouldn't offer an answer if you
don't know.

To OP (Bill)

Try editing /etc/X11/xorg.conf

see the section that looks like this...

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024" "1280x960" "1280x800" "1280x720"
"1152x864" "1152x768" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

(Note that the 'Modes' section is all on one line but will wrap into
multiple lines in this e-mail.)

Add "1400x1050" into that line (make it the first resolution because the
first listed is the first tried).

Then see what happens when you log out and log back in...I don't think
it will take a restart to change it.
