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. If you need to place the projector to one side or another, face it straight ahead (instead of toward the center of the screen), then use the horizontal lens shift dial to center the image.
  
  If the image looks like or , use the remote control to access the Keystone function to correct its shape. Or press the and buttons on the projector's control panel to correct the shape.
  
  Note:You won't have to use the Keystone function to correct the image as long as you place the projector level (not angled up or down) and at a height between the top and bottom of the screen. This produces the best-looking picture. Keystone correction is not available in widescreen format.
