DVI is short for Digital Visual Interface. It's a standard interface created by the Digital Display Working Group (DDWG). The interface is used by electronics manufacturers to convert analog signals into digital signals, this is used by devices such as LCD digital monitors. You will find many modern monitors are now coming with a 'DVI' port to connect to your video card. With just a single plug and connector it helps to encompass both the new digital VGA interfaces. Technically DVI can handle a massive amount of bandwidth, easily in excess of 160 MHz, which means it supports both UXGA and HDTV.
