10. White balance, Luminance adjustment

Approximately 2 Hours should be allowed for warm up before proceeding White-Balance

adjustment.

Before started adjust white balance, please setting the Chroma-7120 MEM. Channel 3 to 6500⁰K colors, MEM.

Channel 4 to 9300⁰K colors, MEM. Channel 9 to 5700⁰K (our 9300 parameter is x=283±28, y=297±28, Y = 175

±20 cd/m², 6500 parameter is x =313±28, y=329±28, Y = 180 ±20 cd/m², and 5700 parameter is x = 328 ±28, y =

344 ±28, Y = 180 ±20 cd/m²)

How to setting MEM.channel you can reference to chroma 7120 user guide or simple use “ SC” key and “ NEXT”

key to modify xyY value and use “ID” key to modify the TEXT description Following is the procedure to do

white-balance adjust

Press MENU and AUTO-ADJUST button during press Power button will activate the factory mode,

Gain adjustment:

Move cursor to “-Factory Setting-” and press MENU key to enter this sub-menu.

Move cursor to “ Factory” and press MENU key.

Move cursor to “ Auto Level” and press MENU key to adjust Gain and Offset automatically;

a. Adjust sRGB (6500⁰K) color-temperature

1. Switch the chroma-7120 to RGB-mode (with press “MODE” button)

2. Switch the MEM.channel to Channel 3 (with up or down arrow on chroma 7120)

3.The LCD-indicator on chroma 7120 will show x = 313 ±28, y = 329 ±28, Y = 180 ±20 cd/m²

4. Adjust the RED on OSD window until chroma 7120 indicator reached the value R=100

5. Adjust the GREEN on OSD, until chroma 7120 indicator reached G=100

6. Adjust the BLUE on OSD, until chroma 7120 indicator reached B=100

7. Repeat above procedure (item 5,6,7) until chroma 7120 RGB value meet the tolerance =100±2

13. Check List

1) After replacing LCD Main board and panel, Check if white-balance is within the specs, then

re-writing DDC is necessary.

The white-balance value for each common color temperature:

9300 parameter is x=283±28, y=297±28, Y = 180 ±10 cd/m²,

6500 parameter is x =313±28, y=329±28, Y = 180 ±10 cd/m²,

5700 parameter is x = 328 ±28, y = 344 ±28, Y = 180 ±10 cd/m²)

The color temperature value above must be up to the situation of x<y. The value of Y should be confirmed

according to different customers. 15” LCD is commonly 180±20cd/cm²（Center）and 17” LCD is required to be

larger than 200cd/cm²(Center). The exact brightness values are confirmed by the checking-regulations of

different customers and different models.

2) Steps of white-balance adjustment for LCD:(Take 17” AOC LCD LM724 for example)

1. Required instruments: Chroma7120、Chroma2325（BGA265A）。

2. First connect the instruments together and turn on the LCD power, then warm up for 30 minutes under full

white screen mode. First press the “Reset” key in the menu to recover factory set as following.

Set Chroma2325 at round-windows mode and make the detecting-head of Chroma7120 aim at the cross

in the middle, the distance between the detecting-head and the cross is 20cm.

3. Set Chroma2325（BGA265A）to be T144（1280*1024/60HZ）and P105 of full white screen. Test if the

white-balance value is within the specs. Please follow the steps below to adjust if it is beyond the specs.

4. Cut the power. Then press MENU key and re-plug power cable at the same time to enter into the factory

mode. See the following pictures.

Select ”F＂,then Select

AUTO LEVEL item.

5. Test white-balance again after Auto Level. Adjustment with hand is necessary if it is beyond the specs.

6. Select 7x00 item to adjust cool color-temperature and select 6x00 to adjust warm color- temperature. It can

reach to the best effect through adjusting R/G/B value if it inclines to green or blue.

Dell E176FPc

7. Select Exit to the upper menu after completing the adjustment. Then press POWER OFF to exit and save it.

3) Steps for writing DDC：

1. Employ PC, and connect the DDC-writing instrument and the instrument that is ready for writing into DDC to

the power of 12V. Connect the signal cable of the latter to D-USB or DVI of DDC-writing instrument (The

data-writing of monitor needs transfer-interface) and link the DDC-writing instrument with PC through printer

interface. (See the schematic picture below)

(Connection for VGA)

(Connection for DVI)

2. Seek the document with the expanded name of .BAT in DDC file of this model. It appears the indication of

“Input Serial No.：＂after dual-click the document to be ready for DDC-writing.

3. Input the serial number of the product (For instance: AOC LM725 is 13 bits), and then press ENTER to start

writing

4. Check the indication of DDC-writing program at the end. When you see the picture as the schematic picture

above, the“Data compare OK!” Means being written well and that’s the end. Please check if the

Manufacturer Name, Vendor Assigned Code, Monitor Name, Serial Number, Week of Manufacture, Year of

Manufacture are right. It will appear “Data compare error! ” To indicate failure if the DDC-writing doesn’t

perform well. Please check the power resource and the connection of the signal cable, then return to step 3

by pressing ENTER and re-do it.

5. You can exit the program by pressing Ctrl plus C, and then cut the signal cable and the power.

6. The following picture is taking AOC LM725 EDID for example.

Dell E176FPc

Notes:

1. Make sure the system time of PC is in accordance with the real time before writing.

2. The schematic picture is just as an example for description; the exact content of the DDC is dependent on

the serial number of the BARCORD of this model.

3. Data DDC-writing needs a transfer interface.

Instruction：DDC-writing needs 4 files:

1. Barcode.txt (Supply Barcode length and flow number)

2. *.EXE (DDC-writing program)

3. WR.bat (Group order file for cycling utilization of *EXE, and dual-click this file when perform

DDC-writing)

4. W.dat (The content with 128 bits of DDC)
