Setting up a presentation
To make presentations, you can attach a projector to your computer through the HDMI port on your computer.

converter cable on http://www.lenovo.com/accessories/services/index.html.
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 between different display output locations.
Your projector might have one or more audio-input connectors. To project sound, you will need to attach the
combo audio jack on your computer to these connectors, using an audio cable (commercially available).
