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 and screen center are aligned with each other, as shown in Figure 3-3.
