possible for your application while still maintaining a good overall match of
light output from screen-to-screen. By nature, achieving a uniform brightness
will then require a reduced overall brightness—this reduction will help ensure
that you have enough range of adjustment when examining brightness
variables more closely from screen-to-screen, and will help prevent premature
"maxing out" when trying to match to a certain color, zone or projector.

zone, but the value shown represents the current setting for green in this zone.
When other "hidden" values (red or blue) are lower than green, during
adjustment in the White Uniformity menu their values will reach "0" first,
