I assume you also have a GOOD common mode and differential mode filter on
the power line, and the line cords of each are plugged into the same filter.
Also that nothing else is around the equipment, the two pieces are as close
together as possible, and the interconnecting cables are all bundled  and
not hanging like antennas.

If so, sounds like it is egress into the monitor.

I'd just be darned sure the line filter is a good one for common and
differential mode currents.
