My displayed image appear jittery or shaky when I connect a DVD player or VCR to my product. What should I do?

• If you are viewing video from a device connected to the projector's S-Video, HDMI, or Video port or from a device (other than a computer) connected to the projector's Computer1 or Computer2 port and the signal being sent is interlaced (480i/576i/1080i), be sure to turn on the Progressive setting in the Signal menu.
  
  If you are viewing video from a device connected to the projector's S-Video, Video, or HDMI, change the Noise Reduction level in the projector's Signal menu.
  
  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.
