• Be sure the Progressive setting is set to On in the Signal menu. See Adjusting Signal Settings.
  
  If the DVD player has an HDMI port or component video port, you can use an HDMI cable, use a component-to-VGA video cable to connect your DVD player to the projector's Computer1 or Computer2 port, or use a component-to-BNC cable. You can purchase a component-to-VGA video cable (part number ELPKC19) from the Epson Store.
