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 AMD Chipset Driver from the motherboard support DVD. See section 4.2 Support DVD
information for details.
2. Right-click the desktop and select ATI CATALYST(R) Control Center.
3. From the Graphics Settings tree, expand DTV (HDMI™) 1.
4. Click Scaling Options.
5. Move the Underscan/Overscan slider to adjust the overall size of the display on the HDMI™ DTV.
Using this slider increases or decreases any black borders that may be visible around the outside
of the display.
6. To ensure that forcing a custom display mode through the ATI Displays Manager does not create
conflicting resolutions, select the Use the scaling values instead of the customized settings
when the desktop resolution does not match your DFP resolution check box.
The Scaling Options function of the DTV (HDMI™) 1 item in the ATI CATALYST Control
Center is adjustable only when you are using an HDTV compliance resolution such as 480i,
720i, or 1080i.
