About

Digital Visual Interface (DVI) is a video display interface developed by Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor.

DVI was developed to create an industry standard for the transfer of digital video content. The interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-D (digital only), DVI-A (analog only), or DVI-I (digital and analog). Featuring support for analog connections as well, the DVI specification provides optional compatibility with the VGA interface.

This compatibility along with other advantages led to widespread acceptance in the PC industry over other competing digital standards such as Plug and Display (P&D) and Digital Flat Panel (DFP). Though predominantly found in computer devices, DVI is also present in some consumer electronics such as television sets.
