Minimum is '0' (-). Maximum is '100' (+).
Image settings:
Auto Adjust Even though your computer system can recognize your new flat panel monitor on
startup, the 'Auto Adjustment' function will optimize the display settings for use with your particular setup.
NOTE: In most cases, 'Auto Adjust' will produce the best image for your configuration; this function can be directly access via Auto Adjustment
Pixel Clock The 'Phase' and 'Pixel Clock' adjustments allow you to more closely adjust your monitor

OSD Warning Messages A warning message may appear on the screen indicating that the monitor is out of sync.
Cannot Display This Video Mode
Optimum resolution 1280 x1024 60Hz
This means that the monitor cannot synchronize with the signal that it is receiving from the computer. Either the signal is too high or too low for the monitor to use. See Specifications for the Horizontal and Vertical frequency ranges addressable by this monitor. Recommended mode is 1280 X 1024 @ 60Hz.
NOTE: The floating 'Dell - self-test Feature Check' dialog will appear on-screen i f the monitor cannot sense a video signal.
Occasionally, no warning message appears, but the screen is blank. This could also indicate that the monitor is not synchronizing with the computer. See Troublesh ooting for more information.

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/m 6500 parameter is x =313±28, y=329±28, Y = 180 ±10 cd/m
5700 parameter is x = 328 ±28, y = 344 ±28, Y = 180 ±10 cd/m 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 /cm larger than 200cd/cm
2
(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.

)
2
（Center）and 17” LCD is required to be
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 cro ss is 20cm.
3. Set Chroma2325（BGA265A）to be T144（1280*1024/60HZ）an d 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
UTO 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 6x0 0 to adju st warm colo r- te mperatu re. It can reach to the best effect through adjusting R/G/B value if it inclines to green or blue.

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 doe sn’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.

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; th e exact content of the DDC i s 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)
