2.6 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 DVI-D), you can easily enjoy the benets of dual monitor feature
without installing any add-on VGA card to this motherboard. This motherboard also
provides independent display controllers for D-Sub and DVI-D to support dual VGA
output so that D-Sub and DVI-D can drive same or different display contents.
To enable dual monitor feature, please follow the below steps:
1. Connect D-Sub monitor cable to D-Sub port on the I/O panel, or connect DVI-D
monitor cable to DVI-D port on the I/O panel.
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.
