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. See Adjusting Signal Settings.
  
  If the DVD player has a Component Video port, you can use a Component Video cable to connect your DVD player to the projector's Computer (Component Video) port using a VGA-to-component adapter (ELPKC19).
