Dude, as far as I know there are controls (trimpots?)
for making convergence adjustments inside the monitor.
IIRC some had them externally. I'm sure I've done it
in the past, but the method will be particular to
each monitor usually. A tech manual would prove to be
the most helpful. I'm sure there are forums specific
to monitor tweaking and repair also.

A good starting point is macmothership.com. Loads of
links and stuph.
