You just need to adjust different resolutions in the xorg.conf file.
Eg, I have:

Section "Screen"
        Identifier      "Default Screen"
        Device          "ATI1"
        Monitor         "Generic Monitor"
        DefaultDepth    24
...
        SubSection "Display"
                Depth           24
                Modes           "1400x1050"
        EndSubSection
EndSection
Section "Screen"
        Identifier      "Screen2"
        Device          "ATI2"
        Monitor         "External Monitor"
        DefaultDepth    24
...
        SubSection "Display"
                Depth           24
                Modes           "1024x768" "800x600" "640x480"
                #Virtual                1400 1050
        EndSubSection
EndSection

This is the current state of the X server.
