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•If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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 39 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® graphics card, you can designate the other display as the primary 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.
