Digital Visual Interface is an interface for the transmission of video between a source device and a display device.

DVI (Digital Visual Interface) is an interface designed for the transmission of uncompressed video signal between a source device (such as a video card) and a display device (such as a computer monitor). While mostly used for digital signals (as the name implies), some configurations are nonetheless also capable of transmitting analogue signals.

A DVI connector can be one of the following:

  • DVI-D, which can only transmit a digital video signal.
  • DVI-A, which can only transmit an analogue video signal, and is directly compatible with the standard VGA connector.
  • DVI-I, which can transmit both analogue and digital signals.

DVI-D and DVI-I can also have additional pins for a dual-link configuration, which effectively doubles the available video bandwidth, allowing for higher resolutions (up to 2560×1600) or refresh rates.
