Vertical and Horizontal 
Position
Proper placement of the projector relative to the screen will yield a rectangular, 
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in such a way 
that the lens center is aligned with either the top or bottom edge of the screen area, and 
centered horizontally. 
The top of the projected image is even with the lens center when the projector is inverted 
(ceiling-mounted). Likewise, the bottom of the projected image is aligned with the lens 
center when the projector is upright (as in a floor installation). See Figure 3-2.

Folded Optics
In rear-screen applications where space behind the projector is limited, a mirror may be used 
to fold the optical path, as shown in Figure 3-3. The position of the projector and mirror must 
be accurately set. If you are considering this type of installation, contact your dealer for 
assistance.
