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.

I've never seen a video board that put out
digital signals to an EGA/VGA
monitor, though that doesn't mean they don't exist.
I believe there's a new all-digital interface for flat-panel monitors.
