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, 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 don't have an HDMI port, the next best choice is a component Video connection. You'll need the optional VGA to Component adapter ELPKC19. If you can't use an HDMI or component Video connection, connect it with a S-Video, or Video cable.
