DDC, what is it and how does it work??
I'm working on a project and I need to know exactly what DDC is, how it works and what exactly it does. Can any one shed a little light on this??
Much appreciated.

VESA DDC
(VESA Display Data Channel) A VESA standard communications channel between the display adapter and monitor. The DDC is used to pass Extended Display Identification Data (EDID), which is stored in the monitor and describes its characteristics (vendor name, serial number, frequency range, etc.).
DDC requires an additional wire in the cable. The first level implementation (DDC1) provides a unidirectional channel that lets the monitor inform the host of its capabilities. A second bi-directional level (DDC2) allows the host to adjust the monitor.
For example, the monitor's switch settings could be put into a software control panel.

It doesn't look like the complete spec is available on the web. You may have to request a copy of the spec from www.vesa.org .

Correction, you have to purchase a copy of the spec, for US$350. I guess that's why it's not readily available...

Thanks for the help. Don't really intend on shelling out $350 US for that info so this will have to do. Thanks again.
