My displayed image appear jittery or shaky when I connect a DVD player or VCR to my product. What should I do?

• Be sure the Progressive setting is set to On in the Signal menu. If the DVD player has a component video port, you can use a component-to-VGA video cable to connect your DVD player to the projector's computer port.
  
  Note: A component-to-VGA video cable is supplied with the projector.
