There were also some LCD and plasma displays built that came with their
own simple interface card that presented an EGA interface. I used to
have one of these. But the LCD/plasma interface was a proprietary
digital interface, not a normal video signal. If you have one of these
old LCD/plasma systems you need to have the original EGA interface card
that came with it. You cannot substitute a different card.
