The image is not rectangular. What should I do?

• If the image isn't square or rectangular, correct it as described in Adjusting the Image Shape.
  
  The projector automatically corrects vertical keystone distortion (image looks like or ) when it is tilted within a range of 45° up or down.
  
  Note: You can maintain a square or rectangular image by placing the projector directly in front of the screen and keeping it level (not angled up or down). This also produces the best picture quality.
