Installation Considerations

Although the CP2000-XB is carefully engineered to deliver an exceptional quality high-brightness, high-
resolution output, your final display results could still be compromised if the projector is improperly installed.
This subsection discusses issues to consider before proceeding with a permanent installation. Read through to
understand how good positioning will help ensure optimized images at any site.

2.2.1 Screen Types

Front Screen Installations

This projector is intended for use with flat or slightly curved screens, front or rear, ranging from about 5 meters
(16 ft.) to 25 meters (82 ft.) wide. Although flat screens generally offer a low gain similar to a matte white wall
paint—approximately 1 with a viewing angle just under 180°—and are considered most effective when
ambient light is low, this difference in gain may be negligible given the very high light output from this
projector. In addition, incident light reflects equally in all directions so the audience can see the display from
more acute viewing angles. See Figure 2-8.
NOTE: CP2000-XB high-contrast lenses are designed primarily for use with flat screens, but the projector's
depth-of-field range allows the lens to be focused on mildly curved screens as well. While focus remains sharp
in the corners, there may be significant pincushion distortion, primarily at the top of the screen.
