If the supply voltage was reduced to a CRT type monitor, the image size
would start to decrease, and the picture may have some blooming with the
increase of brightness. What is being described here, is the common effect
of a strong magnetic field to the mask and the deflection system of a CRT.

to put an example as to why i say voltage drop is from experience.
i am not saying that is the problem how ever, i have had monitors and
Tv's produce that same effect due to the unit on the same line that
wasn't able to maintain the voltage to a minimum required level for the
regulator and thus caused strange bending and waving effects in the
image.
if this is the case, in some designs these effects are not healthy.

that is all i have to say about that one. i just find it hard to
believe that 5 feet of space is generating that kind of field, i think
i would have second thoughts about where i would be sitting on a
regular bases when the nuker was running.
