Alignment Procedure

1

1. Alignment procedure (for function adjustment)

A. Preparation:

1. Setup input timing ICL-605, 32-Grays pattern.

2. Setup unit and keep it warm up at least 30 minutes.

B. Timing adjustment:

1. Enter factory setting area (press “LEFT”, “EXIT” and then press “SOFTPOWER”).

2. Check the settings to following values:

Contrast = 50

Brightness = 90

Volume = 30

OSD time = 20

Color = sRGB

Language = English

Then, turn off the monitor power.

3. Turn on power enter user area.

C. Color balance adjustment:

1. Enter factory setting area (press “LEFT”, “EXIT” and then press “SOFTPOWER”).

2. Setup input timing UVGA7, 4-Grays pattern.

3. Press “AUTO”, waiting for press <right> message.

4. Press “RIGHT” to Calibrate ADC.

5. Setup input timing ICL-605, 32 -Gray pattern.

6. Checking if the picture is no good, reject this monitor.

D. Color adjustment:

1. Setup input timing ICL-605, white pattern.

2. Measure color temperature by Minolta CA-110 (or equivalent equipment).

3. Alignment the color temperature Bluish, Reddish & sRGB. The color temperature
specification as follows:

X+- 0.283+(-) 0.03 White Balance

(Bluish, 9300K set on OSD)

Y+- 0.297+(-) 0.03
