- That's not the power supply -- does it make a sort of humming noise while
- doing this? I can almost guarantee you that this is merely the degaussing
- circuitry at work. The purpose of degaussing is to realign (internally)
- the monitor with ambient magnetic fields. You may have experienced at some
- time (usually with older, larger monitors) that after _moving_ them, or
- turning them more than about 15 degrees, that the color kinda goes funny
- for a while? That's because the monitor had adjusted itself to the magnetic
- field patterns around it in its previous position. Then, you shift the
- field's orientation, and it takes a while before the interaction nullifies.
-
- Degaussing circuitry somehow makes this readjustment automatic, and only
- turns on when it detects the neccesssity(sp?) to do so. If you have another
- monitor nearby, have it turned on, turn on the seiko, degauss it, then
- turn them both off, and then turn the seiko *only* back on, you will notice
- that the colors may be shifted funny, or get effects similar to when you
- hold a magnet to a TV screen... We had acouple of monitors that were next
- to usesless -- because they had to be degaussed manually! Once we learned
- what that little button was for, presto! Three perfect-condition 21" analog/
- RGB multisync monitors! :-) (stop drooling!)
