General Immunity thresholds for computer monitors: 30-450Hz: Approx. 160-170 dBpT 450Hz-15kHz: 100 dBpT
I have generally seen good immunity at frequencies in excess of 15kHz. Tests performed with MIL-461C RS01 loop/audio oscillater+audio amplifier. Monitor most sensitive when disturbance is applied 5 cm away from the outer shell near the yoke coil.

Does anyone have an estimate of the magnetic field immunity levels of recent production computer monitors? What levels, in Gauss or Tesla, do monitors actually start to show disturbance? And at what levels could you expect a typical monitor to be not just annoying, but virtually useless?
