DVI-A
Analogue Only Monitor Cable
DVI-A
monitor cables carrying only the analogue signal, are used where
one end is to mate with a DVI-I connector and the other end with
a standard HD15 connector. NEC screens fitted with only DVI-I inputs
come with such a cable as standard, for connection to analogue only
graphics cards.
The
monitor cable itself is very different for digital signal transmission
compared to analogue. The three coax cores for the RGB signal are
replaced by foil shielded twisted pairs one for each colour plus
a 4th twisted pair for xxxxxxx. The digital signal is very delicate
and effective transmission over 5 metres cannot be guaranteed, which
means that analogue SVGA cables will continue to be used in many
applications e.g. where display units such as plasma screens or
projectors are sited over 10m, from the signal.
