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•If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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

To make presentations, you can connect a projector to your computer through the VGA connector on your computer.

Note: It might take several seconds before the projector displays the image. If you do not see your desktop displayed after 60 seconds, press F7 to switch among different display output locations.

Your projector might have one or more audio-input connectors. To project sound, you need to attach the combo audio connector on your computer to these connectors, using an audio cable (commercially available).

Using dual display

This section introduces the Duplicate and Extend desktop functions that enable you to display output on both the computer display and an external monitor.
