uniform brightness will require a slightly 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 adjacent screen.
‰
USE A “USER” COLOR GAMUT (ADJUSTMENT)—
Always adjust Brightness
Uniformity for a User color gamut defined when you matched primary colors,
and continue to use it for all non-cinema sources displayed on the wall. Your
other color palettes will not necessarily be matched from screen-to-screen.
‰
WHITE UNIFORMITY SLIDEBARS—
White Uniformity slidebar values may not
reduce to “0”. Each slidebar adjusts overall light output in a specific screen
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,
causing the slidebar to stop earlier than expected.
‰
JUDGE BY EYE OR USE A METER—
Good brightness uniformity can be
achieved with either method.
Step 1: General Setup
1a)
Adjust primary colors (see Matching Colors in Multiple Screens) to ensure
matched overall color temperatures and light output between screens.
IMPORTANT
Double-check that all WHITES and LIGHT OUTPUT are well-matched.
1b)
Enable the
Brightness
Uniformity
checkbox. This will
enable access to the
uniformity controls
and will apply the
settings to your
image.
1c)
Select the 13 Point test pattern for display. This pattern provides 9 screen
“zones” with 13 targets.
FOR BEST RESULTS: Rather than
examining the CENTER of each zone
when assessing Brightness Uniformity
adjustments, focus on extreme EDGES
as indicated in the illustration at right.
