2.8.2 Fold Mirror Adjustment

If a corner or edge of the image is missing (after prime
lens offset is ruled out), this may indicate the fold
mirror has become misaligned with the rest of the
optical system, resulting in cropping of data. To
correct this issue, use the two adjustment screws that
are accessible through the base of the projector. See
Figure 2-29.
• To raise or lower the image, adjust the screw
closest to the operator's side (right side, when fac-
ing screen).
• To move the image left or right, adjust the screw
furthest from the operator's side.

Calibrating the System

It is recommended to use the web user interface for calibrating image color performance and defining
electronic screen masking. This is required in your particular installation for creating individual Projector
Configuration Files (PCFs) and specific source files necessary for proper display of incoming material.
Through the web user interface you can also define the system/network configuration for communication links
to the projector, transmitting information to and from the CP2000-ZX via an Ethernet or RS-232 connection.

2.9.1 Color Calibration

After the CP2000-ZX is installed and all components are mechanically aligned for optimized light output and
geometry at the screen, its electronic system processing must be calibrated to ensure accurate color display in
the new environment. In this one-time global calibration, the installer measures initial colors at the screen from
the center of the viewing audience location, also called SMPTE seats, and enters this data—called Measured
Color Gamut Data (MCGD)—into the web user interface. The software then calculates precise corrections
needed for regaining the desired color performance—called Target Color Gamut Data (TCGD)—and
essentially compensates for the type of port window (if present), screen, lens, light output, ambient light and
other current environmental factors that affect color performance. Results are defined in a file, activated, and
downloaded to projector memory to be used as a basis for all future displays.
If there are changes to the environment in the future (for example, a new screen is installed), the CP2000-ZX
should be re-calibrated. Also note that correction for proper color balance sometimes reduces overall light
output. NOTE: Onsite MCGD files are not provided with the projector and must be created by the installer.
Multiple gamut files can be saved for use in different situations, such as when an auxiliary lens is swapped on
and off the projector. These saved gamut files are accessible from the Channel: Page 2 menu on the web user
interface or from the Edit Channel: Measured Color submenu using the CDP.

2.9.2 Electronic Screen Masking

Image geometry can be corrected through the web user interface using the masking tool for precision cropping
in the Admin: Screen menu. The effect is similar to aperture plate filing typically done for correcting images
from film projectors. NOTE: Masking adjustments are global. Multiple screen formats can be saved for use
with various sources. These saved screen formats are selectable from the Channel: Edit Channel from the
web user interface and the Edit Channel: Screen Format using the CDP.
