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"
".
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 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.

There is no
H
ardware DDC (DDC IC) anymore. Main EEPROM stores
all factory settings and DDC data (EDID code) which is also called
Software DDC. The following section describes the connection and
procedure for Software DDC application. The main EEPROM can be re-
programmed by enabling '' factory memory data write'' function on the
DDC program (EDID46.EXE).
