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?
