86 | NEC DISPLAY WALL CALIBRATOR - USER’S GUIDE
If a color shows as dim but noiseless, it indicates the current setting value is too high, and should be reduced.
Hint 1: The edges of the screen may be very different from the center. Concentrate on the noise at the center of the
screen.
Hint 2: In some cases it may be difcult to nd the correct level when only adjusting one color. Try adjusting another
color then go back to rst color.
Hint 3: If it is not possible to locate the correct gain levels that show noise, check the source signal to make sure it is of
sufcient voltage level. Proceed again in small increments.
Hint 4: Using the IR Remote may be faster than using the Analog Gain slider controls in the software due to the time it
takes to update each control.
The following table shows how the screen color will change as the GAIN values are adjusted:
SCREEN COLOR GAIN 01 Value GAIN 02 Value GAIN 03 Value
Black INCORRECT INCORRECT INCORRECT
Gray TOO HIGH TOO HIGH TOO HIGH
Red Noise OK INCORRECT INCORRECT
Green Noise INCORRECT OK INCORRECT
Blue Noise INCORRECT INCORRECT OK
Yellow Noise OK OK INCORRECT
Cyan Noise INCORRECT OK OK
Magenta Noise OK INCORRECT OK
White Noise OK OK OK
11. In the software, click the Normal LUT button to restore the normal LUT. This process will take less than 1 minute.
12. Repeat for all other displays.
13. When complete, evaluate the adjustments using a white video signal from the analog source.
