Whether you are working on a detailed art project, multiple files at once, or simple wish to open more windows, you may need to connect multiple monitors to your Mac. In this video, Gary Rosenzweig from MacMost.com shows you how to hook up another screen to your computer and make the most out of your desktop space.
