2.13.3 Admin: MCGD Menu

The Admin: MCGD menu allows users 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 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 (TCGDs) will then be consistently achieved from source-to-
source and from site-to-site. If the environment degrades or changes (such as if a wide angle converter
lens is swapped on and off, or if an internal optical module is replaced), create 1 or more new MCGDs,
naming them as desired. 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.

Summary of Admin: MCGD Menu Options

• Measured MCGD: Activate each color, which projects a special full-field test pattern and enter the
XY coordinates measured at the screen with a PR650 Spectrometer. For each color (R,G,B and
White), record the native "uncorrected" XY color coordinates measured at the screen. These values
simply represent the currently viewable primary colors and collectively (when saved) define the raw
color performance "reference point" for this projector in the current environment. Each radio button
activates the corresponding full-field test pattern of the native color so that measurements can be
taken. For example, to measure the red coordinates, click the Red radio button to change the screen
