VGA, DVI, S-Video and other video connectors pinouts
DMS-59 is a 59-pin electrical connector generally used for computer video cards. It provides two DVI/VGA outputs on a single connector.

 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 support two high resolution displays, and a full-height card (with two DMS-59 connectors) up to four high resolution displays.

The DMS-59 connector is used by ATI, NVIDIA, and Matrox for video cards sold in Lenovo Thinkcentres, Viglen Genies and Omninos, Dell, HP, and Sun 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.

An adapter cable is needed for conversion from DMS-59 to DVI or VGA, and different types of adapter cables exist. The connector is four pins high and 15 pins wide, with a single pin missing from the top row, in a D-shaped shell, with thumbscrews.
