WHaT Is WHITe FIelD UnIFORMITY?
• No area of the screen appears more red, green or blue than another
• No area of the screen appears brighter than another
• Color and light output from one screen closely matches adjacent screens
Before You Begin
read through the entire procedure before attempting to adjust White Field Uniformity controls,
and keep in mind the following checklist of prerequisites and guidelines:
 aDJUsT COlORs FIRsT — always adjust the primary colors as described in the “Matching
Colors in Multiple Screens” procedure (above) before attempting to work with White Field
Uniformity. This ensures that primary colors, color temperature, and maximized light output
are all well matched from one screen to another. These matches are needed before you can
achieve good White Field Uniformity results.
 RUn laMP FOR 100 HOURs — Light output and White Field Uniformity can vary significantly
during the first 100 hours of lamp use. For best results with new lamps, either set up White
Field Uniformity after this period, or do an initial setup and re-check at 100 hours
 seT laMP POWeR — ensure that 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 White Field 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 slIDe baRs — White Uniformity slide bar values may not reduce to
“0”. Each slide bar 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 slide bar to stop earlier than expected.
 JUDGe bY eYe OR Use a MeTeR — Good White Field Uniformity can be achieved with
either.
