DVI Connectors

The Digital Visual Interface, or DVI, was developed to transmit digital information from a computer to a digital display. It uses transition minimized differential signaling (TMDS) to efficiently transmit large amounts of digital data from the source to the display, resulting in a high-quality image. DVI technology is now commonly found not only on personal computers but also on TVs, DVD players and HDTV set-top boxes. The DVI interface uses a connector similar to a DB-style connection, but instead of round pins, it features flattened pins designed to ensure a solid connection with the mating connector. The DVI connector on a device is categorized into one of three types, depending on the signals it supports: DVI-I (integrated, combining digital and analog signals in the same connector; digital can be single or dual link), DVI-D (digital only, supporting single link or dual link), and DVI-A (analog only).
