All Macintosh computers including laptops have the ability to connect to a variety of external displays. Whether the display is a standard monitor, a large screen or a projector, the Mac will connect with little set-up required. LCD projectors have become popular for displaying presentations and slide shows from software such as Microsoft PowerPoint or Apple's Keynote. Connecting a projector to a Mac is relatively straightforward provided you have the necessary video adaptors.

Tips and warnings
- Determine what type of video connector your projector uses, the most common being a VGA connector. Since the MacBook Pro has a DVI video connector, you must purchase a DVI to VGA adaptor (see Resources). If your projector uses another type of connector, you must purchase the appropriate adaptor from Apple.
- Consult the projector's documentation to determine if there is a procedure to activate the projector's display if you don't see an image on the projector after connecting and powering on the projector and the MacBook.
- Make sure to remove the projector's lens cover.
