Digital Visual Interface. A digital graphics interface standard, using a large type of graphics connector. The RGB signals are transferred differentially and digitally, differing from the VGA analog standard. This standard is used for interfacing between graphics sources such as a PC, grabber card, set top box etc, and a graphics acceptors such as a digital monitor, Plasma screen, video/data projector and similar devices. Control data is also transferred via the DVI interface. The DVI-D connector (24 pins) uses only the digital format, while the DVI-I connector (29 pins) transfers digital and “old” analog VGA type signals on additional pins. The DVI signals - due to their high-speed digital contents - are sensitive to cable length, and are prone to digital problems like the Cliff-effect and jitter, similar to the DV or SDI signals.
