I just got an Apple 2-page monitor, and installed it to the left of my
old Apple color monitor.
There is a magnetic coupling between them that causes the right half of
the 2-page display to swim about a few pixels-worth, even with the color
monitor 4" away. The problem goes away if I turn the color monitor off,
and the color display is not noticeably affected by the 2-page neighbor.
The result is nausea...
Is there a commercial shield available that will solve this problem?
Does anyone have experience with ad-hoc solutions that worked?

We have the identical problem. We placed an aluminum rack panel (basically a large sheet of aluminum) between the monitors. This causes the problem to be much less noticeable but still there. I think that a grounded steel panel might help further (steel being ferrous while aluminum is not). I have not tried this. Ultimately, we placed the monitors one above the other. That cured the problem permanently. Apple says, "Oh, yeah we know about this.....move the monitors apart.", no duh! P.S. I have also seen the problem between a MacSE/30 and a Panasonic color monitor attached to it. -- = John DeRosa, Motorola, Inc, Cellular Infrastructure Group = = e-mail: ...uunet!motcid!derosaj, motcid!derosaj@uunet.uu.net = = Applelink: N1111 = =I do not hold by employer responsible for any information in this message =
