A DVI-D port that only supported digital signals (no VGA)
Digital Visual Interface (DVI) is a video display interface developed and introduced by the Digital Display Working Group (DDWG) in 1999. The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of digital video content.
Background
This interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). Featuring support for analog connections, the DVI specification is compatible with the VGA interface.[1] This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards, such as VESA Plug and Display (P&D) and Digital Flat Panel (DFP).[2] Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players.
Variants from Apple

Apple Computer's first implementation of DVI was the Apple Display Connector (ADC), a proprietary variant introduced in July 2000 in the Power Mac G4 and G4 Cube. Apple began phasing out its use of ADC in favor of standard DVI with the Power Mac G5 and matching Apple Cinema Displays in June 2004.[3]
Apple implemented a smaller variant, Mini-DVI, in its 1 GHz and faster 12-inch PowerBook G4 models. An even smaller variant, Micro-DVI, was implemented in the 1st-generation MacBook Air (early 2008 only). Both connectors types were phased out in favor of Mini DisplayPort.[4]
