Adjusting Your Mac's Display to Project

It is horribly frustrating to prepare a great presentation and then be unable to use the images you planned for your audience. The PDF below assumes that you have already connected your projector (or other external monitor) to your Mac. These instructions can be used with either desktops or laptops connected to compatible external (or additional) monitors. Make sure your additional display is properly connected and powered on before beginning.
