1.5.2.4. WHITE 
BALANCE 
This adjustment is normally unnecessary. The luminance and tint between screens can be 
adjusted in CSC. 
Used to adjust a color temperature. Three memories: LOW, MIDDLE and HIGH can be used to 
save in. 
[Procedure] 
1.  Press [TEST] button three times to display the adjustment white. 
2.  Select WHITE BALANCE in INSTALLATION in the system menu. 
3.  Select HIGH, MIDDLE or LOW. 
4.  Adjust R, G and B values. 
1.5.2.5. GRADATION 
Used to adjust gradation if the differences of luminance/tint level between each screen are 
prominent. 
Set adequate values in consideration of the balance of brightness and uniformity. If you increase 
it in the plus direction excessively, you have to decrease the total gain. 
[Procedure] 
(In the instance of a display wall that consists of four screens) 
1.  Press [TEST] button three times to display the adjustment white. 
2.  Select GRADATION in MAINTENANCE in the system menu. 
3.  Select WHITE, R, G or B to open the each gradation adjustment menu. 
4.  Adjust to match the luminance/tint level in the edge of adjacent screens (gray area in the 
lower left figure) using the adjustment item A in the lower right table. In this case, align darker 
parts with brighter, considering uniformity in a single screen. 
5.  Adjust to match the luminance/tint level in the 4 corners connecting area (area “a” in the 
lower left figure) using the adjustment item B. 
6.  Adjust to match the luminance/tint level in the fringe of screens (area “b” and “c”). At first, 
adjust whole edges with the adjustment item A and then compensate corner areas with the 
item B. 
7.  Repeat the steps from 4 to 6 so as to uniform the luminance/tint level of all colors.
