An LCD would be ideal but alas none are available
(low cost) that have more than the basic LCD drivers. The DELL laptop
LCD I have is typical of the MONO 640x480 displays and the "video" input
is not like a crt in timing or signals. For example the display is
really two 640x240 running in parallel with seperate video for each.
Hand built logic to do that costs enough in power and design time to
make it unappealing or no better than a good mono crt unless I resort
to Gals/FPGAs (design effort and cost prohibitive for a one up).
There are (were?) a few vendors that made very nice single chip solutions
for converting base VGA into something an LCD could use.
Hitachi?
