2.8 Dual Monitor and Surround Display Features
Dual Monitor Feature
This motherboard supports dual monitor feature. With the internal VGA output sup-
port (D-Sub and HDMI), you can easily enjoy the benefits of dual monitor feature
without installing any add-on VGA cards to this motherboard. This motherboard also
provides independent display controllers for D-Sub and HDMI to support dual VGA
output so that D-sub and HDMI can drive same or different display contents.
To enable dual monitor feature, please follow the steps below:
1. Connect a D-Sub monitor cable to the D-Sub port on the I/O panel and connect a
HDMI monitor cable to the HDMI port on the I/O panel.
2. If you have already installed the onboard VGA driver from our support CD to your
system, you can freely enjoy the benefits of dual monitor function after your
system boots. If you haven't installed the onboard VGA driver yet, please install
the onboard VGA driver from our support CD to your system and restart your
computer.
