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. See
Figure 3-2.
Figure 3-2. Projector Placement
Vertical and Horizontal
Lens Shift
If it is not possible to align the projector and screen as shown in Figure 3-2, you can use
the lens shift controls to center the image on the screen. Lens shift is generally expressed
as a percentage of the screen height or width, as shown in
Figure 3-3 and Figure 3-4.
