TERMINOLOGY
DDC
Short form for Display Data Channel. It is a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform the video card about its properties, such as maximum resolution and color depth. The video card can then use this information to ensure that the user is presented with valid options for configuring the display.
DDWG
Digital Display Working Group DDWG are the creators of the DVI specification.
DVI
