Extended Display Identification Data is a VESA standard data format that contains basic information about a display device and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the monitor name and serial number.
The information is stored in the display and is used to communicate with the system through a Display Data Channel (DDC), which sites between the display device and the PC graphics adapter. The system uses this information for configuration purposes, so the monitor and system can work together.
Note: - If a display device has digital input ports, like DVI or HDMI, but without EDID in its main board, the display device will show no image while the input source is digital signal.
- The EDID Upgrade for P7270I/P7280/P7270I Refresh/P7280 Refresh/P7290 is the same, here we take P7270I for example.
- After EDID upgraded, do "Default Language Reset".
6-6 Un-lock SNID and Default Language Reset (for P7280 Refresh/P7270I Refresh/P7290)
For P7280 Refresh/P7270I Refresh:- Hold on "Power" button then plug in the Power Cord
Note: At this moment , Power LED flashes blue and red about 2 seconds until Power LED flashes blue only for 2 seconds, please release the "Power" button.
- After flashing, LED is in steady condition and you can judge the actions as the following table:
Note: If it is fail, please do the actions as above steps.
For P7290:- Plug in power cord.
