What purpose does DVI serve on a video card

[bullion416]

What exactly is DVI used for on a video card? Is it a good thing to have?

DVI is Digital Video Interface, I believe. It is for the newer monitors (mostly LCDs) where the video image is kept digital (binary) and not converted to analog through a RAMDAC. It is suppossed to provide better picture quality. Most graphics cards made today have it along with an older analog connection. Many also come with converters to change DVI to an analog connection.

DVI is digital. Most LCD's have DVI inputs. DVI looks better.
