This is not strictly true, there is genlock for the video output of the O2, but
not for
the graphics pipe (& yes this is very annoying).

Well it definitely does to PAL, so I would be very surprised if not to ntsc, but
as
I said before remember that the graphics pipe is not genlocked to the video pipe,
so you will drop frames & the only locked signal is the video out (as opposed to
monitor).

I've cut in a bit late, but I suspect you want to sync the monitor outputs in
which case
Angus is totally correct, the graphics pipe on an O2 is not genlockable (well you
can actually
set the kernel variable, but all hell breaks lose).
