STEP 1:
General Setup
1a) Adjust primary colors (see Matching Colors in Multiple Screens). This ensures
matched overall color temperatures and light output between screens.
IMPORTANT
Double-check that all WHITES and LIGHT OUTPUT are
well matched.
See Step 3f of Matching Colors in Multiple Screens

1b) Enable Brightness Uniformity by entering a checkmark in the checkbox. This
enables access to the uniformity controls and applies the settings to your image.

1d) Select User 1 in the Color Setup window
(accessed through Image Settings).

IMPORTANT
Never change color temperature white levels in color-
matched applications!

center. If any of the areas differ, use the White Uniformity menu to match edges
and corners to the center as described below. Begin with the screen exhibiting the
most obvious variations in light output.
◊
Adjust edge White Uniformity first – note that each edge adjustment also
affects the rest of the screen slightly. Keep all edges just slightly lower than
the center light output rather than matching light output precisely. Otherwise,
it may not be possible to brighten the corners (typically the dimmest areas of
