My projected image appears jittery or shaky when viewing video or moving images. What should I do?

• 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 On in the Signal menu. See Adjusting Signal Settings. Turn this setting on also if you are viewing video from a device (other than a computer) connected to the projector's Computer (Component Video) or HDMI (EX5200/EX7200 only) port and the signal being sent is interlaced (480i/576i/1080i).
  
  Note:
  Turning on the Progressive setting converts interlaced signals into progressive signals which can improve picture quality when viewing video or moving images. This setting should be turned off when viewing still images.
  
  For best results, connect your video equipment to the HDMI (High-Definition Multimedia Interface) port (EX5200/EX7200 only), if possible. If your equipment doesn't support HDMI, connect it to one of the following ports (highest quality listed first): Computer (Component Video) [for component video], S-Video, or Video (for composite video).
