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 if 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 Troubleshooting 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/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.
56
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.
57
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)
