Thanks, Frank. There were two switches on the card
(actually called "composite video interface") and I
tried all four combinations. With one setting I got
garbage. With the other three, the small multi-screen
look, but still very hard to read. I have a few
security monitors in the garage that I'll look at to
see if they're the right frequency.
