new lamps, either set up Brightness Uniformity after this period, or do an
initial setup and re-check at 100 hours.
SET LAMP POWER—
Make sure each “Lamp Power” setting is as high as
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 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 projector.
USE A “USER” COLOR TEMPERATURE—
Always adjust Brightness Uniformity
for a
User
color temperature defined when you matched primary colors, and
continue to use it for all sources displayed on the wall. Your other color
temperatures 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.
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.
