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• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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.
If the computer output does not appear on the DVI monitor, do the following:
• For Windows 7:
1. Press Ctrl+Alt+F12. The Intel ® Graphics and Media Control Panel window opens.
2. Select Advanced Mode and click OK.
3. Select Multiple Displays.
4. In the Operating Mode field, select one of the following options depending on your needs and follow
the instructions on the screen to complete other configurations.
