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 and Signal menus to finish adjusting the picture.
  
  If you are viewing video from a device connected to the projector's S-Video or Video port, be sure to set the Progressive setting to Video.
  
  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): Component (for component video), S-Video, or Video (for composite video).
