Using The Extend Desktop Function - Lenovo ThinkPad Edge L330 User Manual

• Click the Monitor tab and select a color value from the Colors field.
• Click OK.
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• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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 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.
Considerations for using the Extend desktop function
• When an application using DirectDraw or Direct3D is played in full-screen mode, it is shown only on the
primary display.

DOS; the other display is blacked out.

by doing the following:
