Troubleshooting on HDTV overscaling or underscaling:
If your desktop is extending beyond the viewable display area or the desktop or
image is not filling the entire display area while using the onboard HDMI out port
and the HDMI cable, you can resize the desktop appearing on your HDTV screen.
To resize your HDTV desktop:
1. Install NVIDIA Chipset Driver Program from the motherboard support DVD.
2. Right-click the desktop and select NVIDIA Control Panel.
3. Under Video & Television, select Resize HDTV desktop.
4. Select Resize my desktop and click Resize Desktop.
5. A full-screen adjustment tool
appears. Use the scroll bar to
resize the desktop to fit your display
device. Click OK to exit.
The Resize my desktop function in the NVIDIA Control Panel appears only
when you are using an HDTV compliance resolution such as 480i, 720i, or
1080i.
