We have a Dell 2407 widescreen monitor and an NVIDIA Quadro NVS 285 video card. I was not able to get the screen working at 1920×1200 resolution until I added a Modeline line to the monitor section of my xorg.conf file.

Here is the relevant part of xorg.conf to get this setup working properly.

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Dell 2407WFP (Digital)"
        DisplaySize  520        330
        HorizSync    30.0 - 83.0
        VertRefresh  56.0 - 76.0
        Option      "dpms"
        Modeline    "1920x1200" 154.128 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync

EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "nv"
        VendorName  "Videocard vendor"
        BoardName   "NVIDIA Quadro NVS 285"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1920x1200" "1280x960" 
        EndSubSection
EndSection
