If it's serialized then it's really moving along! if you've got 1K pixels at
a
nominally 65 MHz pixel rate with 24 bits per pixel ... I assume the designers at
least use three channels, one for each color, so as to reduce that to 8 bits per
pixel, right?
For most applications, the distance from the "box" to the display isn't far
at
all, but I can see the benefit where a large display might be desirable, as in a
classroom or demonstration environment.
Nevertheless, aside from relatively small signal losses, there isn't a big
advantage, aside from the fact that every display manufacturer can process the
signal however he prefers.
That makes it possible to use essentially the same signal arrangement, which
seems a mite risky to me. It makes me wonder whether the DE15's I've seen on
the flat-panel displays are for a standard VGA signal arrangement or something
else.
What sort of connector is used for the serialized digital arrangement?

Subject: RE: Converting TTL monitor to Analog
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.
Not if a serial video bitstream were used. It's actually easier to use this
than
an analogue feed over any significant distance.
