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.
