How do I get Windows XP to display video files on a computer projector?
First, make sure the computer display is set to LCD+CRT, usually by pressing Fn + one of the function keys displaying dual output. Next go to control panel, and open the display properties icon. Choose Settings, and Advanced. Choose Overlay Controls and Video Mirror Controls. Choose Primary display or Secondary display in Full Screen Device. Click OK. The specific settings may vary on different machines, but should follow a similar method.
