        I've certainly seen VGA-type multisync monitors damaged due
to people trying to push the resolutions up beyond what the monitor
was meant to do. Today with all the PnP stuff it's not seen as often
as it was with DOS and the tweaking manually though.

        Looking at to references I have here, I see two monitors
right off the bat that take a TTL signal as input: both the Tandy
CM-1 and VM-1 monitors, not to mention the current crop of DVI LCD's
out there.
