Using the video output connectors
The video output connectors on the dock consist of one DVI-D video output connector and one DVI-I video
output connector. You can simultaneously connect two external monitors to the dock using the two video
output connectors. You do not have to disconnect the dock from your notebook computer each time when
you connect the external monitors to the video output connectors.
To use the video output connectors, connect the DVI cable of the external monitors to the video output
connectors on the dock.
You also can connect an external monitor with a VGA connector to the dock using a DVI-I to VGA adapter.
To use the DVI-I to VGA adapter, do the following:
1. Connect the DVI-I to VGA adapter to the DVI-I video output connector on the dock.
2. Tighten the two screws on the DVI-I to VGA adapter.

3. Connect the VGA connector of the external monitor to the DVI-I to VGA adapter using a VGA cable.
You can adjust video settings to customize the use of the dock. For more information, see “Working with
the dock utility” on page 13.
Note: For better performance, occasionally adjust the external monitor to realign its settings with the video
output of the dock. For more information about the adjustment procedure, refer to the documentation
that comes with your external monitor.
