What is DVI?
DVI stands for Digital Visual Interface and was created by the Digital Display Working Group (DDWG). Its original design included conversion of analog signals into digital signals to accommodate both analog and digital monitors. Data is transmitted by using the transition-minimized differential signaling (TMDS) protocol and providing a digital signal from the PC's graphics subsystem to the display. There are three "flavors" of DVI: DVI-A for analog signals such as VGA, DVI-D for digital signals (the DVI signal all consumer home theater products use) and DVI-I that is a combination of DVI-D and DVI-A.
DVI-D supports two levels of performance; single link and dual link. While all consumer home electronics gear is currently designed around the DVI-D single link standard, a dual link cable is 100% single-link compatible and offers the benefit of future adaptability for wide bandwidth applications.
DVI-D is a fully digital video transport protocol that supports all digital video formats including 480i, 480p, 540p, 720p, 1080i and 1080p.
