Installation

Vertical and Horizontal

Proper placement of the projector relative to the screen will yield a rectangular,

Position

 

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 3-3.

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

Lens Shift

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 3-4and Figure 3-5.
