E. Writing EDID file:
1. Setup a PC with DDC card.
2. Connect PC to monitor with a D-sub(DVI) signal cable.
3. Please refer to the C212 for the correct EDID file.
4. Runs the writing program to write the EDID file into EEPROM .
5. Read EEPROM data and confirm it to match with the C212 document definition.
