How can I improve the image quality?

• Make sure you've selected the best Color Mode for your picture and viewing environment. Then use the Image menu to finish adjusting the picture.
  
  If you are viewing video from a device connected to the projector's S-Video or Video port, adjust the Progressive and Noise Reduction settings if available for your video source.
  
  For best results, connect your video equipment to the HDMI (High-Definition Multimedia Interface) port, if possible. If your equipment doesn't support HDMI, connect it to one of the following ports (highest quality listed first): Computer with a VGA-to-component adapter cable (for component video), S-Video, or Video (for composite video).
  
  Note: A component-to-VGA video cable is supplied with the projector.
