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• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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 the Extend desktop function
Your computer supports the Extend desktop function. 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 37.
Considerations for using the Extend desktop function
• If you want to show DOS full-screen while in Extend desktop mode, only the primary display shows
DOS; the other display is blacked out.
• If your computer has the Intel
®
