A DVI-D cable is a digital video display connector used in computers. It supports the same resolutions as VGA which has been the analog standard for many years. Digital signals do not suffer from timing errors that can sometimes reduce the clarity of an image delivered with VGA.
Note that there are two other formats. DVI-A uses the DVI connector but it carries an analog signal identical to that of VGA connector. A DVI-I carries both digital and analog signals and therefore provides two video links within the same cable.
Finally, DVI digital signals are compatible with HDMI video signals. DVI does not carry sound in either digital or analog video formats whereas HDMI supports sound within the same cable.

FranWell, there isn't really a difference in what the DVI cable does its the way the pins are layed out. You get 4 different types:
- DVI-D (digital only)
- DVI-A (analog only)
- DVI-I (integrated, digital & analog)
- M1-DA (integrated, digital, analog & USB)
The way you define these is by the pin layout, each pin is labled 1 - 24 and then you get 4 C pins that make the cross.
Thus, DVI-D is commonly used for connecting computers to TV's, LCD monitors or projectors, but when buying these cables, the pins will only fall into the places needed making these very easy cables to install because no matter what DVI cable you buy they will always connect to the DVI port you have.
