        No, the D'break sync rates are usually out of the multisync
monitor range. Mine can't sync to VSYNC rates below 58Hz or something,
for instance. But I have not yet tried with older multisync monitors
(damn, I sold my Amiga A3000 monitor...)

        That's too great! he he

        I'll get busy as as I return home!

        And it may be fruitful to visit the junkyard this weekend for
good-old multisync monitors.
