6. Checking if the picture is no good, reject this monitor.
7. To check the power consumption by disabling “burn-in mode” setting
8. To clear user data and program complete DDC data to monitor by IIC bus communication.
5.2.5 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.
