I don't know about the rest, but Apple's DVI connector has 24
pins. I'm not sure how many are on their latest connector, the ADC.
It goes back to something similar to what the NeXT did: it carries
power, video, and USB through the single ADC connector to/from the
LCD. Belkin makes an adapter that converts between the two though,
at least for connecting DVI displays to ADC graphics cards.

What sort of digital interface would such devices use?
They'd have
to have lots
of wires, e.g. 26 or so pairs, if the thing is using 24-bit color. Perish the
thought someone would use more color depth than that! It's hard to imagine
they'd do that. The number of wires that have to transport high-frequency
signal is the reason the analog is still so difficult to surpass.
After all, a 26-pair shielded cable with an appropriate connector, made in the
US, would immediately become the most costly component in a computer
system. I
doubt a computer maker would go for that, as the 20" monitor (@~$300-$400) is
presently the most costly component. That would essentially make the 20"
display and cable more than 2/3 the cost of the computer.
