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.

    Adjust the display resolution of the projector, if desired, by selecting the appropriate resolution from the resolutions menu displayed on the projector screen.

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.
