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.
But isn't the digital signal less dependent on absolute signal integrity?
After all, if there can only be two levels, making out the difference can't be
all that difficult. This also seems to hold true WRT my successful use of
long, thin, unshielded cables for EGA and CGA monitors without any ghosting.
