DVI stands for (D)igital (V)ideo (I)nterface.
DVI is a popular form of video interface technology made to maximize the quality of flat panel LCD monitors and modem video graphics cards. It is a replacement for the P&D Plug & Display standard, and a step up from the digital-only DFP format for older flat panels. DVI cables are becoming increasingly popular with video card manufacturers, and most cards nowadays include both a VGA and a DVI output port.

Three types of DVI connections : DVI-Digital, DVI-Analog, and DVI-Integrated (Digital & Analog).
