2.10 Dual Monitor and Surround Display

Dual Monitor

This motherboard supports dual monitor. With the internal VGA output support (D-Sub HDMI and Thunderbolt), you can easily enjoy the benefits of dual monitor without in- stalling any add-on VGA cards to this motherboard. This motherboard also provides independent display controllers for D-Sub, HDMI and Thunderbolt to support dual VGA output so that the D-Sub, HDMI and Thunderbolt can drive the same or differ- ent display contents.

To enable dual monitor, please follow the steps below:

1.Connect a D-Sub monitor cable to the D-Sub port on the I/O panel, connect a HDMI monitor cable to the HDMI port on the I/O panel, or connect a Thunderbolt monitor cable to the Thunderbolt ports on the I/O panel.

D-Sub port

HDMI port Thunderbolt ports

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.

D-Sub, HDMI and Thunderbolt monitors cannot be enabled at the same time. You can only choose two of them.
