Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
DisplayPort displays use one TMDS/DisplayPort transmitter and no clock signal. An active DisplayPort adapter can convert a DisplayPort signal to another type of signal—like VGA, single-link DVI, or dual-link DVI; or HDMI if more than two non-DisplayPort displays must be connected to a Radeon HD 5000 series graphics card.

A Y-style breakout cable is needed for the transition from the DMS-59 output (digital + analogue) to DVI (digital) or VGA (analogue), and different types of adapter cables exist. The connector is four pins high and 15 pins wide, with a single pin missing from the bottom row, in a D-shaped shell, with thumbscrews.
Project VGA aims to create a low-budget, open-source VGA-compatible video card. [104] The Open Graphics Project aims to create an open-hardware GPU. The Open Graphics Device v1 has dual DVI-I outputs and a 100-pin IDC connector. In September 2010, the first 25 OGD1 boards were made available for grant application and purchase. [105]
The ICs supported a USB 2.0 input and a 24-bit RGB output or LVDS output. Additional chips needed in the design are an EEPROM and DDR Memory. If the design required an Analog RGB (VGA) or DVI output an additional chip was needed to convert the 24-bit RGB output to VGA or DVI. [21]
Five variants are: DVI-I single link, DVI-I dual link, DVI-D single link, DVI-D dual link, and DVI-A. Male Mini-DVI plug on top of a 12-inch PowerBook G4; female port is second from left. Mini-DVI: VGA, DVI, television. Apple Computer alternative to Mini-VGA. Often now replaced by Mini DisplayPort. Female Micro-DVI port (rightmost) on MacBook ...

For analog VGA/YPbPr and dual-link DVI, a powered active adapter is required for compatibility and does not rely on dual mode. Active VGA adapters are powered directly by the DisplayPort connector, while active dual-link DVI adapters typically rely on an external power source such as USB.
