Considerations for attaching an external monitor
• When installing an operating system, you must install the display driver for your monitor that is supplied
with the computer, and the Monitor INF le that is supplied with the external monitor.
• If you set a resolution higher than the resolution you are using on the panel, and use a panel 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 or other pointing device.
Note: The virtual screen function is not supported on Windows 7.
• If the external monitor you are using is outdated, the resolution and the refresh rate may be limited.

Using the Extend desktop function
Your computer supports a function named the Extend desktop. With the Extend desktop function, you
can display output on both the computer display and an external monitor. You can also display different
desktop images on each monitor.
You can use the Extend desktop function without changing any settings. If the function does not work, refer
to “Enabling the Extend desktop function” on page 50
to enable it.
Considerations for using the Extend desktop function
• If you want to show DOS full-screen while in the Extend desktop mode, only the primary display shows
DOS; the other display is blacked out.
If your computer has the Intel

display by doing the following:
1. Press Ctrl+Alt+Fn+F12. The Intel CUI window opens.
2. Select Extended Desktop.
3. Change the setting to designate the primary display.
• When an application using the DirectDraw or the Direct3D is played in full-screen mode, it is shown
only on the primary display.
