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 3-2.

Shift

If it is not possible to align the projector and screen as shown in Figure 3-2, you can use

the mechanical 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.
