Setting up a presentation
To display information and make presentations, you can connect a data projector to your computer through
the VGA connector on your computer.
Note:
It may take several seconds before the projector displays the image. If you do not see your desktop
displayed after 60 seconds, try pressing F7 to switch between different display output locations.
Your projector might have one or more audio-input connectors. To project sound, you need to attach the
combo audio jack on your computer to these connectors, using an audio cable (commercially available).
