Admin: MCGD Menu

The Admin: MCGD menu allows you to record measurements for currently projected "uncorrected" colors.
Recording the projector's uncorrected color performance is typically completed as a final step (like a
calibration) after installation. For this one-time procedure, the installer measures initial "native" (i.e.,
uncorrected) colors at the screen, enters the data as Measured Color Gamut Data (MCGD) and typically saves
an MCGD file called "OnSite". By default, the projector uses this MCGD to calculate and implement precise
processing modifications needed to achieve any target color gamut on screen, essentially compensating for the
type of port window, screen, lens, light output, ambient light and other current environmental factors
influencing on-screen colors. These various industry standards for color performance Target Color Gamut Data
(TCGDs) will then be consistently achieved from source-to-source and from site-to-site. If the environment
degrades or changes (such as if an anamorphic lens is swapped on and off) or if an internal optical module is
replaced, create one or more new MCGD files. To use an MCGD file as the reference file for target color
processing (such as with a certain source and/or lens), select it in the Channel: Page 2 menu.

Activate each color which projects a special full-field test pattern and enter the x/y coordinates mea-
sured at the screen with a PR650 Spectrometer. See Measured MCGD Notes below.
This button collects the current color values entered for Measured (MCGD), where you can save them
as a new "OnSite" MCGD file or as a different MCGD file with a different name. NOTE: A new
"OnSite" overwrites any previously defined "OnSite" file and becomes the default reference point for
all future color processing. The old "OnSite" file cannot be recovered. See Save Notes below.
This button enables you to return to the gamut menu settings that were present when you opened the
menu. See Restore Notes below.
