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 to your computer's video port and to the projector's Computer1 (VGA) port. (Do not connect it to the projector's Computer2 (VGA) port; this will not work.)
If your image colors look wrong, try changing the Input Signal setting to RGB.
Note: Some LCD monitors may not be able to display the image correctly. If you have trouble displaying the image, connect a multiscan monitor. If you're projecting computer images, make sure the computer's refresh rate is set to 60 Hz or greater.
