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 keystone slider to correct the image.
  
  If the image looks like or , make sure the projector is not tilted up or down, then use the vertical keystone buttons to adjust the image. See Positioning the Image for details.
  
  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.
  
  For best image quality place the projector directly in front of the screen and minimize the need for horizontal keystone correction.
