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 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 or DisplayPort connector, if possible. If your equipment doesn't support HDMI, connect it to one of the following ports (highest quality listed first): Computer1 or Computer2 with a VGA-to-component adapter cable (for component video), or Video (for composite video).
