• Check the video switcher program to see if the DVD input is being sent to the the correct display device (instructions w/image here)
• Check if the viewsonic switch is turned on and display the correct input channel
  • The Viewsonic switch has a green LED indicating power on status. If this LED is not lit, then power on the switch using the power button
  • Using the video switcher, display the DVD output on either of the monitors. If the screen is black or green then the input channel to the switch is incorrect. Cycle through the input channels by pressing the input button repeatedly, till you find the DVD channel. The monitor should now display the movie.
