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 30° up or down. If keystone correction isn't automatically performed, enable Auto Keystone for the Keystone setting in the Settings menu or hold down the or buttons on top of the projector until the image is rectangular. After correction, your image will be slightly smaller. See Customizing Projector Features.
  
  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.
