Only part of the picture is displayed or the image looks distorted. What should I do?

• Check the following:
  • Press the Aspect button on the remote control to select a different setting. See Adjusting the Aspect Ratio.
  • If projecting from a computer, press the Auto button on the remote control. Also make sure the image Position setting is correct in the Signal menu.
  • Press the Esc button on the remote control to cancel the E-Zoom function.
  • You also may need to modify existing presentation files if you created them for a different resolution. See your software documentation for specific information.
  • Make sure your computer's resolution setting is correct. Ideally, it should be 1280 × 800 to match the projector's native resolution for the PowerLite 1730W, or 1024 × 768 for the PowerLite 1720. If this option isn't available, select one of the other compatible video formats.
  • Check the projector's Resolution setting. Select Normal or Wide, depending on the size of your computer's display panel.
  • Make sure your computer is not set to display an extended desktop.
