I am guessing that you have your monitor connected via VGA cable and not
via DVI.

I have this monitor, and I found it to work better then the Optiquest I
had a few weeks ago.  In my case, I was using the video-amd (Geode
chipset, not ATI) to drive the display.  Here is what I saw on the

Configure resolution to 1920x1200 in xorg.conf

        Section "Screen"
                Identifier "Screen0"
                Device     "Card0"
                Monitor    "Monitor0"
                SubSection "Display"
                        Viewport   0 0
                        Depth     24
                        Modes "1920x1200"

Screen comes up, but when I run:

        xeyes -geomery 1920x1200

... xeyes went off screen, because the LCD was actually displaying
1600x1200, not 1920x1200 as X thought it was.  I say again: the X server
and the driver think that the display is 1920x1200, and the LCD is doing
some magic to "fix" it because the timings are out of sync.

I think it's very hardware specific/driver; but there may be some X bug.

Can you confirm that you get the same results?  What driver/card are you
