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.
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.
The

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.
6.
To ensure that forcing a custom display mode through the ATI Displays Manager does
not create conflicting resolutions, select the
