Whats the difference between DVI-I and DVI-D?
It’s important to first note that “DVI” (Digital Video Interface) refers to the connector, or interface, only. It’s application can vary. There are three main types of DVI; DVI-I, DVI-D and a third one which is rarely mentioned, DVI-A. This latter one is DVI “Analogue”, which is quite obviously analogue only. This is essentially VGA (RGB-HV) in a different plug. DVI-D is at the other end of the scale, being pure Digital video only. DVI-I combines the two, containing both analogue and digital cores. DVI-I does NOT convert ananlogue to digital. Rather it just provides a convenient connection to offer analogue or digital in the one cable.
