Electrical connector
An electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or...

(analog), 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.
The application for DMS-59 is to support a higher density of video displays, in a similar amount of connector space to a DVI connector. DMS-59 supports two DVI Single Link digital channels or two VGA analog channels from a single connector. The compact size lets a half-height card

computers. Some confusion has been caused by the fact that vendors label cards with DMS-59 as "supports DVI", but the cards do not have DVI connectors built-in. Such cards, when equipped with only the VGA connector adapter cable, cannot be connected to a monitor with only a DVI-D input. A DMS-59 to DVI adapter cable needs to be used with such monitors.

connector, which can also be found on some earlier graphics cards. These ports are similar to the DMS-59 port, but have all 60 pins present, whereas DMS-59 has one pin (pin 58) blocked. You cannot put a connector plug with all 60 pins (such as a Molex 88766-7610 DVI-I splitter) into a properly keyed DMS-59 socket.
