How do I correct overscan?


I would like to correct the overscan on my TV, but I have no idea how. I'd estimate that I'm losing about 25-30 pixels on each side.

Here's my xorg.conf:
# Xorg configuration created by system-config-display

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us+inet"

Section "Monitor"
        Identifier   "Monitor0"
        ModelName    "LCD Panel 1920x1080"
        HorizSync    31.5 - 67.0
        VertRefresh  56.0 - 65.0
        Option      "dpms"

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
Here's my graphics card's section from lspci -vv:

Not related to your query, you might want to add
 Option      "AddARGBGLXVisuals" "True"
to Section Device.
