I purchased a monitor in Ireland and am about to move to New Zealand - is it true that the monitor will not work correctly after changing hemispheres - and is this fixable? of does it become a boat anchor?

The following was taken from Webopedia.com (http://www.webopedia.com/DidYouKnow/Hardware_Software/2002/MonitorHemispheres.asp)

The monitor you are using with your computer may be affected by which hemisphere of the earth you are in. The Northern and Southern hemispheres of the earth have different magnetic fields, each pulling toward its respective pole. Monitors with cathode ray tubes, which are the majority of desktop monitors in use today, are manufactured specifically for which hemisphere they are going to be used in. CRT monitors work by moving electron beams back and forth behind the screen, and the earth's magnetic fields act on the electron beams, pulling them toward the field. A monitor calibrated for the Northern hemisphere can still be used in the Southern hemisphere, but the colors and the image would be slightly skewed. Most major monitor manufacturers give users the controls to manually adjust the image.
LCD monitors are not affected by this phenomenon.

So it looks as though you will be OK aslong as you canadjust the tilt etc on your monitor.

If you align it with the magnetic azimuth properly, you shouldn't have any problems :D

Rubbish! :-) Very funny, but fatally flawed.

I've come across this before. You can test it before you leave.
All you do is turn the monitor off , turn it upside down , then turn it back on.If the picture is good then it wil work in Godzone.BTW you'll have to turn it off, turn it up the right way again and turn it back on to reverse the process, and don't worry you can't stuff it unless you drop it !!!

You may still get a small lack of convergence though, that the user controls wont fix. That can only be adjusted by the convergence rings on the neck of the tube, and they are usually very securely 'glued'. (Convergence is when the colours dont overlap properly, so instead of a single colour line you may see colours side by side).
