VGA, DVI, S-Video and other video connectors pinouts
DisplayPort is a digital display interface.

DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to transmit audio, USB, and other forms of data.

Dual-mode DisplayPort can directly emit single-link HDMI and DVI signals using a simple passive adapter that adjusts for the lower voltages required by DisplayPort. When dual-mode chipset detects that a DVI or HDMI passive adapter is attached, it switches to DVI/HDMI mode which uses the 4-lane main DisplayPort link and the AUX channel link to transmit 3 TMDS signals, a clock signal and Display Data Channel data/clock. Dual-mode ports are marked with the DP++ logo; most current DisplayPort graphics cards and monitors offer this mode.

A notable limitation is that dual-mode can only transmit single-link DVI/HDMI, as the number of pins in the DisplayPort connector is insufficient for dual-link connections; an active converter is needed for Dual-Link DVI (and analog component video such as VGA, since it employs digital to analog conversion). Active conversion can be powered by +3.3 V wire in the DisplayPort connector, but some active adapters require external power.
