It depends on what signal is being sent.  For example, I have an IBM
monitor designed for connecting to an RS/6000.  RS/6000s use a connector
that is very similar to SGIs.  However, RS/6000s can either have sync
signals over the green pin or over separate pins.  The SGIs are strictly
sync-on-green, and use some of the additional pins for monitor ID
probing.  If I don't let the sense pins float, the monitor sees the
sense probe as a weird sync signal.

Try reversing the sync cables, then.  It sounds like you're getting H
for V and V for H.  The ordering of the BNC cables is not a standard.
