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• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.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