How do I connect a monitor to my product so I can simultaneously view images on the monitor and from my product?

• Make sure the projector and computer are turned off. Disconnect your monitor cable from your computer's video port and connect it to the projector's Monitor Out port. Then connect the VGA computer cable that came with your projector to your computer's video port and to the projector's Computer1 port. (Do not connect it to the projector's Computer2 port; this will not work.)
  
  If your image colors look wrong, try changing the Computer Input setting to RGB.
