Notes on MCGD, TCGD and ColorMAX User settings
TCGD (see the next section)
The parameters entered on the
TCGD
page establish the target settings that the
projector needs to aim for, in order to give a specified colour gamut.
MCGD (see this section)
The parameters entered on the
MCGD
page establish the starting settings, from
which the projector will calculate what adjustments are necessary to achieve the
color gamut specified on the
TCGD
page.
Only one set of
MCGD
data can be stored on the projector, but many more can be
stored on a computer, and retrieved using the
MCGD page
controls.
