2.7 Dual Monitor and Surround Display Features
Dual Monitor Feature
This motherboard supports dual monitor feature. With the internal VGA output sup-
port (DVI-D, D-Sub and HDMI), you can easily enjoy the benefi ts of dual monitor
feature without installing any add-on VGA card to this motherboard. This mother-
board also provides independent display controllers for DVI-D, D-Sub and HDMI to
support dual VGA output so that DVI-D, D-sub and HDMI can drive same or different
display contents.
To enable dual monitor feature, please follow the below steps:
1. Connect DVI-D monitor cable to DVI-D port on the I/O panel, connect D-Sub
monitor cable to D-Sub port on the I/O panel, or connect HDMI monitor cable to
HDMI port on the I/O panel.

already, you can freely enjoy the benefi ts of dual monitor function after your
system boots. If you haven't installed onboard VGA driver yet, please install
onboard VGA driver from our support CD to your system and restart your
computer.
1. D-Sub, DVI-D and HDMI monitors cannot be enabled at the same
time. You can only choose the combination: DVI-D + HDMI, or HDMI
+ D-Sub.
2. When you playback HDCP-protected video from Blu-ray (BD) or
HD-DVD disc, the content will be displayed only in one of the two
monitors instead of both monitors.
3. To support Dual-link DVI monitor, please do not use D-Sub and HDMI
ports. Please connect the DVI monitor cable to the DVI port only.
