Weird. What is this monitor?
It is not getting your DPI (dots per inch). I have to fix mine, because
it is detected wrongly:

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        VendorName  "Videocard vendor"
        BoardName   "nVidia Corporation NV34 [GeForce FX 5200]"
        Option      "NoLogo" "true"
        Option      "UseEdidDpi" "FALSE"
# Detected is wrong: 95 x 96
        Option      "DPI" "96 x 96" <---- this is for a 17" Samsung LCD
EndSection

Check whether you are loading "ddc", in Section "Module". In theory it uses
whatever it gets from the monitor, ignoring anything you supply.

I think you have to find out the modelines for your monitor.
Recently, I read this text. It is for ATI, but the concepts are useful,
anyway.
