This can happen if the back of the two displays are too close to one
another, or if another monitor or electromagnetic-based device is close
to the display.  Try moving the units a little further away from each
other, or away from a potiential source of electromagnetism (like a TV
set or the like).

I've seen the same phenomena on a VAXstation monitor when a VT220 terminal
is on and next to the monitor.
