(Which has XGA [1024x768] 60Hz PC Format output
signal : 100% Color Bar Pattern shown in Fig. 2 )
It is very import to use correct adjustment pattern like Fig.2.
O
- If Minimum Black Level and/or Maximum White Level
is not correct, Select 100% Color Bar Pattern.
(1) Method of Auto RGB Color Balance
1) Input the PC 1024x768 @ 60Hz with 100% color bar
pattern like Fig.2. into RGB.
(Ex. MSPG-925FA, model:60, pattern:65)
2) Set the PSM to Standard mode in Picture menu.
3) Press the INSTART key on R/C for adjustment.
4) Press the G (Vol. +) key operate To set , then it becomes
automatically.
5) Auto-RGB OK means adjustment is completed.

6. White Balance

<Notice>
- Before white balance,press the In-start key 2times and do
the reset like Fig1.
- Use the cortez inner pattern(216 gray pattern)
- To enter White-balance mode,press the IN-START key
2times.

=> UART Baud rate : 115200
Pattern Generator (MSPG-925FA etc.)
* Color Temperature & Color Coordinates Setting
When adjusting the Color Temperature of LCD, Color
Analyzer CA-210(Matrix should be corrected through CH9
of CS-1000) should be used.
Adjust the Color Temperature based below adjustment
color coordinates.
Even if CH9 of CA-210 is corrected with Matrix, there may
be many character of Module and Filter.
Therefore Refer to the below Color Coordinates Target.

6.1. Manual white Balance (Inner pattern)
1) Execute CA-210(9CH) Zero Calibration.
2) Execute the SET Heat Run for 30minutes
3) Use cortez inner pattern as below Fig. 4, Supply 216Level
(85 IRE) full screen pattern
4) Enter the White Balance adjustment mode by pressing the
INSTART key twice(White Balance) on R/C.
5) Stick sensor to center of the screen and select each items

6) Adjust with R / G / B Gain using ¢∏/¢∫(VOL £´/£≠) key on
R/C.
7) Adjust it until color coordination becomes as below.
