Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3
A digital current loop uses the absence of current for high (space or break), and the presence of current in the loop for low (mark). [1] This is done to ensure that on normal conditions there is always current flowing and in the event of a line being cut the flow stops indefinitely, immediately raising the alarm of the event usually as the heavy noise of the teleprinter not being synchronized ...

P&D combined analog and digital video with data over USB and FireWire to reduce cable clutter, but the feature creep resulted in an unpopular, expensive connector. [2]: 4 Compaq described DFP as a "transition" step between the analog VGA connector and P&D: DFP was designed by a consortium including Compaq, Hewlett-Packard, and ATI Technologies as a smaller, simpler connector, dropping support ...
[1]: §4.7 Data signals over USB and FireWire also are optional. USB version is not specified, [1]: §8.5 but if supported, it would have been intended for contemporary USB standards. The USB connector is intended for passing mouse movements from a projector's wireless remote to the computer's presentation software and for firmware upgrades. [2]

A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...
The compact size lets a low-profile 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 was used by e.g. AMD , Nvidia and Matrox for video cards sold in some Lenovo ThinkStation models, Viglen Genies and Omninos, Dell, HP and Compaq computers.
