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 83 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 adapter, you can designate the other display as the primary display by doing the following:

1.Press Ctrl+Alt+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.

•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 as follows:

For Windows 7:

1.Connect the external monitor to the monitor connector; then connect the monitor to an electrical outlet.

2.Turn on the external monitor.

3.Press Fn+F7, then select Extend.

To change the resolution for each monitor, do as follows:

1.Right-click on the desktop, and click Screen resolution.

2.Click the Monitor-1icon (for the primary display, the computer display).

3.Select the Resolution of the primary display.

4.Click the Monitor-2icon (for the secondary display, the external display).

5.Select the Resolution of the secondary display.

6.Place the icons for the monitors so that they touch.
