DDC is a communication channel over which the monitor automatically informs the host system (PC) about its capabilities.

DDC protocol includes:

• DDC1/DDC2B: An uni-directional communication channel.
• DDC 2AB/DDC2B+/DDC2Bi: A bi-directional communication channel.

The PC must support DDC functions for this to work.

E-DDC is a protocol based on I²C and used on a bi-directional data channel between the display and host. This protocol accesses devices at I²C address of A0/A1 as well as address 60.

Address 60 is used as a segment register to allow larger amounts of data to be retrieved than is possible using DDC2B protocols.

The protocol is compatible with DDC2B protocols.

This program is designed to have computer equipment manufacturers build circuitry into their products to reduce power consumption when it is not in operation.
