How can I improve the image quality?

• Make sure you've selected the best Color Mode for your picture and viewing environment. See Adjusting the Color Mode. Then use the Image menu to finish adjusting the picture to your liking. See Adjusting Colors and Clarity
  
  If you're connecting from your device's component video ports to the projector's S-Video, Video or Computer (Component Video) port, be sure to set the Progressive setting to On in the Signal menu.
