Considerations for connecting a DVI monitor

Connect a DVI monitor to the expansion unit, and turn on the monitor before you turn on the computer. Otherwise the system cannot recognize that the monitor is connected. If the option for enabling the DVI monitor in the Display Properties window is not displayed, try closing the window and opening it again. If the option still is not displayed, make sure that the connector of the monitor is attached firmly, and repeat the procedure for connecting the monitor.

Using the mini DisplayPort connector

Your computer has a mini DisplayPort connector, which is a digital display interface for connection to various external devices, such as Cathode Ray Tube (CRT) monitors, LCD monitors, projectors, or even high-definition televisions. This compact connector enables a plug-and-play setup and supports adapters that can plug into DVI, VGA, or High-Definition Multimedia Interface (HDMI) connectors.

The mini DisplayPort connector of your computer supports audio as well as video streaming.

Setting up a presentation

To display information and make presentations, you can connect a data projector to your computer through the VGA connector on your computer.

Note: It may take several seconds before the projector displays the image. If you do not see your desktop displayed after 60 seconds, try pressing the F7 key to switch between different display output locations.

Your projector might have one or more audio-input connectors. To project sound, you need to attach the combo audio connector on your computer to these connectors, using an audio cable (commercially available).
