TV picture shakes/jitters/wobbles when using Nvidia 9600GT

Seems to result from the driver defaulting to 50Hz. Hopefully fixed by making the following changes to xorg.conf:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 9600 GT"
Option "FlatPanelProperties" "Scaling = Native"
Option "SecondMonitorVertRefresh" "60i"
EndSection


Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "1"
Option "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: 1920x1080_60i +1680+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection

Green noise displayed on TV with Nvidia 9600GT

Only occurs when the computer is on but not sending a "strong enough" signal.
E.g. only occurs in black areas when something is being displayed or all over the screen when nothing is being displayed. Dissapears when the brightness is increased by computer software / nvidia proprietary driver configuration.
