The new MacBook, MacBook Pro, and MacBook Air each have a Mini Display Port that allows you to connect an external display or projector using an adapter. You can use an external display as your main workspace or to extend your desktop, or you can work in mirrored mode with a projector so you can view what your audience sees.
