Default Twin and different resolution for TV


I've been trying to get my TV connected to my Dell laptop (GeForce 7900S) using TwinView. My desktop resolution is at 1920x1200 and my TV is at 1024x768. The problem is no matter what I do I cannot seem to get the TV ton run at 1024x768 so the TV only displays a partial view of the screen.

The relevant section of my xorg.conf is:

Section "Monitor"
        Identifier   "Monitor0"
        HorizSync    28.0 - 96.0
        VertRefresh  50.0 - 75.0

Section "Device"
        Identifier  "Card0"
        Driver      "nvidia"
        VideoRam    262144
        VendorName  "All"
        BoardName   "All"
        Option      "RenderAccel" "true"
        Option      "CursorShadow" "on"
        Option      "TwinView"
        Option      "TwinViewOrientation" "DFP-0 RightOf TV-0"
        Option      "MetaModes" "1920x1200,1024x768"
        Option      "TVStandard" "PAL-G"
        Option      "TVOutFormat" "SVIDEO"
        Option      "TVOverScan" "0.6"
        Option      "ConnectedMonitor" "DFP-0, TV-0"
#       BusID       "PCI:1:0:0"

Section "Screen"
        Identifier      "Screen0"
        Device  "Card0"
        Monitor "Monitor0"
        DefaultDepth 24
        DefaultColorDepth 24
        SubSection "Display"
                Depth   24
                Modes "1920x1200" "1600x1200" "1024x768" "800x600" "640x480"
        SubSection "Display"
                Depth   32
                Modes "1920x1200" "1600x1200" "1024x768" "800x600" "640x480"
The relevant lines from Xorg.0.log are:

I've been going back and forth with different configuration settings for hours now. Is there anything that I am missing? I am using KDE but do not yet have it compiled with xinerama support though from my understanding this shouldn't affect the screen resolution of the TV?

Any help would be very appreciated.
