3. Operation instructions 3.1 General Instructions Press the power button to turn the monitor on or off. The other control buttons are located at front panel of the monitor. By changing these settings, the picture can be adjusted to your personal preferences. - The power cord should be connected. - Connect the video cable from the monitor to the video card. - Press the power button to turn on the monitor, the power indicator will light up. 3.
Dell E176FPc 3.3 On Screen Menu/Display (OSD) Direct-Access Functions Function Adjustment Method Auto adjustment Use this button to activate automatic setup and adjustment. The following dialog will appear on screen as the monitor self-adjusts to the current input: Auto Adjust In Progress Auto Adjustment button allows the monitor to self-adjust to the incoming video signal. After using 'Auto Adjustment', you can further tune your monitor by using the 'Pixel Clock' and 'Phase' controls in the OSD.
Dell E176FPc 3.4 Adjusting the Picture 1. With the menu off, push the 'MENU' button to open the OSD system and display the main features menu. A Function icons B Main Menu D Sub-Menu name E Resolution C Menu icon 2. Push the - and + buttons to move between the function icons. As you move from one icon to another, the function name is highlighted to reflect the function or group of functions (sub-menus) represented by that icon.
Dell E176FPc Icon Menu Name and Description Sub-menus EXIT This is used to exit out of the 'Main menu'. Positioning: 'Positioning' moves the viewing area around on the monitor screen. Horizontal When making changes to either the 'Horizontal' or 'Vertical' settings, no changes will Vertical occur to the size of the viewing area; the image will simply be shifted in response to your selection/change. Minimum is '0' (-). Maximum is '100' (+).
Dell E176FPc Phase If satisfactory results are not obtained using the 'Phase' adjustment, use the 'Pixel Clock' adjustment and then use 'Phase' again. NOTE: This function may change the width of the display image. Use the 'Horizontal' function of the 'Position' menu to center the display image on the screen. Color Settings: 'Color Settings' adjusts the color temperature and saturation. Normal Preset 'Normal Preset' is selected to obtain the default (factory) color settings.
Dell E176FPc User Preset 'User Preset': Use the plus and minus buttons to increase or decrease each of the three colors (R, G, B) independently, in single digit increments, from '0' to '100'. NOTE: 'Color temperature' is a measure of the 'warmth' of the image colors (red/green/blue). The two available presets ('Blue' and 'Red') favor blue and red accordingly. Select each one to see how each range suits your eye; or utilize the 'User Preset' option to customize the color settings to your exact choice.
Dell E176FPc Language: Language sets the OSD to display in one of five languages (English, Español, Français, Deutsch, Japanese). NOTE: The language chosen affects only the language of the OSD. It has no effect on any software running on the computer. Factory Reset: 'Factory Reset' returns the settings to the factory preset values for the selected group of functions. 'Exit' is used to exit out of 'Factory Reset' menu.

Dell E176FPc 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
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.
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.
