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. 

You can also project from behind the screen or from the ceiling, with 
the projector mounted upside-down: 

To project from overhead, you’ll need the optional ceiling mount 
hardware. (See page 12 for ordering information.) You’ll also need to 
select 

Front/Ceiling

 or 

Rear/Ceiling

 for the 

Projection

 option in the 

Extended menu. To project from the rear, select 

Rear
