Rachel,
The group I used to work for was/is assembling PC controlled
test racks in the USA which we are going to ship to Oz.
We asked a number of monitor manufacturers this question,
and were told that monitors are 'yammed' (I have no idea
where this term comes from) for a particular geographic
location.  In fact, even different areas in the same
hemisphere get different settings (NEC told us that,
I believe).  The difference is in the vertical component of
the earth's magnetic field, which is reversed when you
change hemispheres.  Try turning your monitor upside down-
you will find that the colors go completely blooey.  You
can eliminate some of this with the degauss switch, but not
all of it.  When you turn it back upright, the colors will
again be screwed up.  Don't try this unless you are willing
to accept permanent discoloration of your monitor- you have
been warned.

Sony is affected, any CRT that uses magnetic deflection 
probably is.  Unless you are told specifically that it
will work in both hemispheres, it probably won't.

I assume that Navy /Air Force or any other hardware designed
for use anywhere around the globe has taken these issues
into account, but fixed location computer equipment 
is not expected to have to contend with it.

The bottom line was, we were told and we finally agreed that
buying monitors locally in Oz was the right solution.  Too
bad we had already bought about a dozen of them...

Cheers,
Mark
