I had a similar problem, and the best solution did indeed turn out to
be using a different monitor.

I tried steel sheet -- ex-PC tower case, in fact, about 1/16" thick
(yes, it was a heavy old one) and found that it didn't make enough
difference, even when extended some way (too far for comfort) in front
of the screens.

And don't put a magnet close to the tube. The risk is not magnetising
the shadow mask, but distorting it, and once that's happened there's no
cure. Unless you hold the tube pointy end down and drop it, in the
hope that the bulge will flatten out with the shock ;-) But then you
might have another problem with that tube.
