General
DDC Data Re-programming
In case the DDC data memory IC or main EEPROM which storage all
factory settings were replaced due to a defect, the serial numbers have
to be re-programmed"Analog DDC IC, & EEPROM".
It is advised to re-soldered DDC IC and main EEPROM from the old
board onto the new board if circuit board have been replaced, in this case
the DDC data does not need to be re-programmed.
Additional information
Additional information about DDC (Display Data Channel) may be
obtained from Video Electronics Standards Association (VESA).
Extended Display Identification Data(EDID) information may be also
obtained from VESA.
