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.
Figure 3-2. Projector Placement
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.
