It was my understanding when I last researched this that very few VGA adapters had the hardware support to combine the H and V sync signals on the Green channel's output, yes. That was why SI87 and the other guys (whose name eludes me for the moment) made so much money. MGA were, IIRC, one of the few who did it right, but their cards were all as expensive as the specialty ones, at the time (1995ish). Cheers, -- jra -- Jay R.
