The image is not rectangular. What should I do?

• If the image looks like or , the projector has been placed off to one side of the screen and angled toward it. Face the projector straight ahead (instead of at the center of the screen), then use the horizontal lens shift dial to center the image.
  
  If the image looks like or , make sure the projector is not tilted up or down. If necessary, use the vertical lens shift dial to position the image on the screen.
  
  As a rule of thumb, you can use lens shift to move the image up or down by nearly its full height, and left or right by about one-half its width. See Positioning the Image for details.
  
  Caution:
  Do not try to move the lens by hand, or you may damage the projector. Always use the lens shift dials to change the lens position.
  
  Note:
  You can display a test pattern to help adjust the image position by pressing the Pattern button on the remote control. Press the Esc button to turn off the test pattern.
