viewing angle just less than 180°. This type of screen reflects incident light equally in all

Screen Size: Choose a screen size that is appropriate for your lens and application. The

primary viewing distance be 1.5 times the screen width.
To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect

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.

Adjusting the Projection 
Angle 
If the screen is significantly higher or lower than the projector, you can also tilt the 
projector at a slight angle. In a ceiling installation, you do this by adjusting the ceiling 
mount. 
If you do this, you may need to shift the image using the on-screen display (OSD) controls, 
to compensate. For detailed instructions, refer to
