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. , this adapter cable was listed as obsolete by its primary vendor

Computers. Some confusion has been caused by the fact that vendors label cards with DMS-59 as "supports DVI", but the cards have no DVI connectors built-in. Such cards, when equipped with only a 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. The DMS-59 connector is derived from the LFH-60

connector, which could be found in some earlier graphics cards. These ports are similar to DMS-59, but have all 60 pins present, whereas DMS-59 has one pin (pin 58) blocked. A connector plug with all 60 pins (such as a Molex 88766-7610 DVI-I splitter) does not fit into a properly keyed DMS-59 socket. A Dual-DVI breakout cable can be used in connection with two passive DVI-to-HDMI adapters to feed modern displays with HDMI inputs, while using a DMS-59 graphics card, since the DVI signals are electrically identical to HDMI signals and do not require any kind of conversion.
