I can't play movies from my computer on my product. What should I do?

• If all computer programs display correctly through the projector except the video player software and a black box appears where the movie should appear and you're using a laptop, you can try turning off the video signal going to the built-in LCD screen and display only through the projector. Please consult your laptop's documentation for instructions on how to disable the internal LCD display.
  
  Note: Most Windows applications and video cards do not support the playing of video files on two displays at the same time.
