How to Connect to a projector (Windows 7)


You can connect your computer to a projector to give a presentation on a large screen.

The instructions below describe how to connect to a projector by plugging the projector cable into a video port on your computer. This is the most common way to connect a projector.

You can also connect to some projectors (called network projectors) over a network. This allows you to give a presentation over a network if you aren’t in the same room, or even the same building, as the projector. To see if your projector has this network capability, check the information that came with the projector or contact the manufacturer.

To connect to a projector

  1. Make sure the projector is turned on, and then plug the projector cable into a video port on your computer.


    • Projectors use VGA or DVI cables. You must plug the cable into a matching video port on your computer. Although some computers have both types of video ports, most laptops just have one type. Some projectors can be connected to a USB port on your computer witha USB cable.
