DVI-I vs DVI-D Video Cables
Note the DVI-D in the picture
on the left. The "D" in DVI-D represents
Digital meaning that it can only be used to connect to a purely digital
monitor. Now look at the DVI-I cable on the
right, you will notice there are 4 extra little pins on this one. The "I"
in DVI-I stands for Integraded meaning that it integrates both
digital to digital as well as analog to analog connections.
DVI digital and analog formats are
non-interchangeable. This means that a DVI-D cable will not work on an analog
system, nor a DVI-A on a digital system. See DVI to VGA adapters below.

DVI to VGA Adapters |
|
To
connect a digital source to an analog display, or vice versa you will
need a DVI-D
to VGA adapter (shown left). This DVI to VGA
adapter will convert to the lowest common denominator,
which in
this case would be analog.
For example, let's say
you have a
high
end video card which has digital outputs by default, but you
have older analog (VGA) monitors that you want to connect it to.
You would use an adapter like this to convert from the video cards from
digital to analog. One side of this adapter will connect to the digital
video card, the other would connect your VGA monitor cable.
