- Has to do with the degauss coil. The Earth's magnetic field is enough to
- distort either very large or very high quality color displays. When I sold
- home electronics as a summer job one year, our 30 inch color TV's had a
- small switch in the back for Northern or Southern hemispheres.

- Reminds me of the color monitor geometry & convergence calibration
- procedures used for a Mac big-screen display company I once worked for. The
- procedure began with "1. Face East" (referring to the device). I was sure
- it was a joke, until it was explained to me that when the shadow mask is
- parallel to the N-S magnetic field, it provides the most central skew of
- adjustments point for an arbitrary position of usage in the field.
