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 file that is supplied 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• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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 dual displays
This section introduces the Extend desktop function that enables you to display output (the same or different)
on both the computer display and an external monitor.
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 also can 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 36 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.
• You can designate the other display as the primary display by doing the following:
1. Right-click on the desktop, then select Screen resolution.
2. Select Extend these displays in Multiple Displays.
3. Change the setting to designate the primary display.
• When a program using DirectDraw or Direct3D is played in full-screen mode, it is shown only on the
primary display.
• You cannot use the display switching function when you are in the Extend desktop mode.
