Setting the Monitor Impedance
If you can switch the impedance values on your monitor, use the
following recommended settings:
• RGB video input: 75 Ohm
• Sync: 2.2 kOhm
Try other 'Sync' settings if you cannot achieve a stable video
image.
If the impedance setting options are 'High' and 'Low' only, try
