Notes:

so affects the throw distances as shown here.

Proper placement of the projector relative to the screen will yield a rectangular,
perfectly-centered image that completely fills the screen.							Position

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 3-2.
