adjustment)

It is a VESA regulation. A PC or a MNT will display an optimal 

resolution  through  information  sharing  without  any  necessity 

of user input. It is a realization of "Plug and Play".

▪ W/B adj. Objective & How-it-works

(1) Objective: To reduce each Panel's W/B deviation

(2)  How-it-works : When R/G/B gain in the OSD is at 192, it 

means the panel is at its Full Dynamic Range. In order to 

prevent saturation of Full Dynamic range and data, one 

of R/G/B is fixed at 192, and the other two is lowered to 

find the desired value. 

(3) Adjustment condition : normal temperature

1) Surrounding Temperature : 25 °C ± 5 °C

2) Warm-up time: About 5 Min

3) Surrounding Humidity : 20 % ~ 80 %

(1) Color Analyzer: CA-210 (LED Module : CH 14)

(2)  Adjustment Computer(During auto adj., RS-232C protocol 

is needed)

(3) Adjustment Remote control

(4)  Video Signal Generator MSPG-925F 720p/204-Gray

(Model: 217, Pattern: 49)

-> Only when internal pattern is not available

▪ Color Analyzer Matrix should be calibrated using CS-100.

<Command Format>

- LEN: Number of Data Byte to be sent

- CMD: Command

- VAL: FOS Data value

- CS: Checksum of sent data

- A: Acknowledge

Ex) [Send: JA_00_DD] / [Ack: A_00_okDDX]

▪ RS-232C Command used during auto-adjustment.

Ex)  wb 00 00   ->  Begin white balance auto-adj.

 

wb 00 10   ->  Gain adj.

 

ja 00 ff   ->  Adj. data

 

jb 00 c0

 

...

 

...

 

wb 00 1f   → Gain adj. completed

    *(wb 00 20(Start), wb 00 2f(end)) → Off-set adj.

 

wb 00 ff   → End white balance auto-adj.

▪ Adj. Map

(1) Auto adj. method

1) Set TV in adj. mode using P-Only key.

2)  Zero  calibrate  probe  then  place  it  on  the  center  of  the 

Display.

3) Connect Cable.(RS-232C to USB)

4) Select mode in adj. Program and begin adj.

5)  When adj. is complete (OK Sign), check adj. status pre 

mode. (Warm, Medium, Cool)

6) Remove probe and RS-232C cable to complete adj.

▪  W/B Adj. must begin as start command “wb 00 00” , and 

finish as end command “wb 00 ff”, and Adj. offset if need.

(2) Manual adjustment. method

1) Set TV in Adj. mode using P-Only key.

2)  Zero Calibrate the probe of Color Analyzer, then place it 

on the center of LCD module within 10 cm of the surface.

3)  Press ADJ key → EZ adjust using adj. R/C → 7. White-

Balance then press the cursor to the right(key ►).

(When right key(►) is pressed 216 Gray internal pattern 

will be displayed)

4)  One of R Gain / G Gain / B Gain should be fixed at 192, 

and the rest will be lowered to meet the desired value.

5)  Adjustment  is  performed  in  COOL,  MEDIUM,  WARM  3 

modes of color temperature.

 ▪  If  internal  pattern  is  not  available,  use  RF  input.  In  EZ 

Adj.  menu  7.White  Balance,  you  can  select  one  of  2 

Test-pattern: ON, OFF. Default is inner(ON). By selecting 

OFF, you can adjust using RF signal in 216 Gray pattern.
