Try to place the projector directly in front of the center of the screen, facing it toward the screen squarely. If the projector isn't positioned this way, the image will be "keystone" shaped, instead of square or rectangular. If you place the projector below the level of the screen, you'll have to tilt it up by extending the front adjustable foot, as described on page 38. This also causes the image to lose its rectangular shape, but the Auto Keystone feature corrects the distortion automatically. If the image does not regain its rectangular shape, the tilt angle is greater than 30° or the Auto Keystone feature may have been disabled. To turn it on, see page 61. To adjust it manually, see page 39. note The Auto Keystone feature corrects vertical distortion automatically. For more information, see page 39.
