[comp.sys.mac.hardware] Two monitors next to each other => screen vibrates => how to stop it?

I have an Apple Color (13") Monitor and an E-Machines Z21 standing next to
each other. The picture on the Z21 vibrates. According to Tech Support I
have this beacuse of the different refresh rates of the two monitors. When
I move the 2 monitors on distance > 6" the vibration stops. The Tech Support
tells me that the only way to stop the vibration (w/o moving them apart) is to
put a mu-metal shiled between them, but this is costly.

Questions: what the heck is mu-metal (greek mu, that is, \mu in \TeX\),
           where to get it and how much it would cost me.

Please respond by email, I will summarize answers on the Net. Thanks!!! Paul
