1.5.2. Color balance adjustment
You can adjust luminance and tint between each screen of a display wall. In principle, they
should be adjusted according to (3) CSC adjustment. However, follow (2) BLACK LEVEL, (4)
WHITE BALANCE and (5) GRADATION adjustments, if necessary.
After that, set TARGET COLOR and SENSOR to maintain the uniformity over the long term.

luminance level.

in the adjustment white.
2. Select BLACK LEVEL in INSTALLATION in the system menu.
3. Select R-, G- or B-LEVEL and adjust each color level in black.
