Considerations for attaching 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 stick or another pointing device.

•If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.

Changing display settings

You can change the display settings, such as the display resolution, font size, and so on.

To change the display settings, do the following:

1.Go to Control Panel and click Appearance and Personalization.

2.Click Display for further configuration.

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 31.

Considerations for using the Extend desktop function

•If you want to show DOSx full-screen while in Extend desktop mode, only the primary display shows DOS; the other display is blacked out.

•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.

Enabling the Extend desktop function

To enable the Extend desktop function, do the following:

1.Connect the external monitor to the mini DisplayPort connector or VGA connector of your computer; then connect the monitor to an electrical outlet.

2.Turn on the external monitor.

3.Press F7, then select Extend.
