The Digital Visual Interface (DVI) is a video interface standard designed to provide very high visual quality on digital display devices such as flat panel LCD computer displays and digital projectors. It was developed by an industry consortium, the Digital Display Working Group (DDWG) to replace the "legacy analog technology" VGA connector standard.It is designed for carrying uncompressed digital video data to a display. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).
DVI to HDMI
DVI is mostly compatible with HDMI. The main difference is that DVI typically carries no audio data in its TMDS channel, although increasingly, modern PC video hardware is providing audio, allowing the PC to send audiovisual data to a high definition television with an HDMI input. If a PC's DVI output does not provide audio, it can be patched in as part of the DVI to HDMI adapter.
