Setting Up the Projector
15
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 37. 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 15° or the Auto Keystone feature may have been disabled. To
turn it on, see page 58. To adjust it manually, see page 38.
Other Installations
You can also project from behind the screen or from the ceiling, with
the projector mounted upside-down:
