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
Depending on the model, your computer might have 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.
Using the Thunderbolt connector
Depending on the model, your computer might have a Thunderbolt connector. It enables you to connect
your computer to a device that is compatible with the Thunderbolt interface or Mini DisplayPort interface,
such as CRT monitors, LCD monitors, projectors, or high-definition televisions. The Thunderbolt connector
has the same appearance as the Mini DisplayPort connector other than the icon. If you connect a device that
is compatible with the Mini DisplayPort interface, it generates Mini DisplayPort signals automatically.
Setting up a presentation
To display information and make presentations, you can connect a data projector to your computer through
the VGA connector, Mini DisplayPort connector, or Thunderbolt connector on your computer.
Notes:
• If the projector connector is not compatible with the Mini DisplayPort connector or Thunderbolt connector
on your computer, you can use a convert cable to establish the connection. Convert cables are available
as options from Lenovo at http://www.lenovo.com/essentials.
• Use a Mini DisplayPort certified cable with Mini DisplayPort icon ( ) to connect the device for
stable functionality.
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
audio connector on your computer to these connectors, using an audio cable (commercially available).
