Considerations for connecting an external monitor
• When installing an operating system, you must install the display driver for your monitor that is provided
with the computer, and the monitor INF file that is provided with the external monitor.
• If you set a resolution higher than the resolution you are using on the computer monitor, and use an
external monitor that does not support that resolution, take advantage of the virtual screen function,
which enables you to display only a part of the high-resolution screen image your computer produces.
You can see other parts of the image by moving the screen with the TrackPoint pointing device or another
pointing device.
• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.
Using a DVI monitor
If your computer has one of the following optional docking stations, you can use a Digital Visual Interface
(DVI) monitor through the DVI connector of that unit:
• ThinkPad Pro Dock
• ThinkPad Ultra Dock
Notes:
• The screen mode that can be used depends on the specifications of the DVI monitor.
• Before you connect a DVI monitor, make sure that the computer is connected to the expansion unit and
works properly.
To connect a DVI monitor, do the following:
1. Turn off the computer.
2. Connect a DVI monitor to the DVI connector of the expansion unit, and then connect the monitor
to an electrical outlet.
3. Turn on the DVI monitor and the computer.
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.
