On our Macintosh called the "common use mac", we have all
sorts of bells and whistles, cd-rom, scanner, DaynaFile,
120Meg, 8meg, IICX with both a 19" gray scale and a 12" RGB
monitors (both apple brand).

My problem is that the rgb monitor causes extreme jitter
in the gray scale monitor.  This is confirmed by powering
off the RGB monitor and verifying that the jitter disappears.
We have reduced the problem somewhat by placing a aluminum rack
panel between the monitors.  Most likely a grounded steel
panel would fix it altogether but that is not the point.

The point is, what is wrong that causes this problem in the
first place?  The repair techs say that everything is ok on
the monitors.
