- But, in my experience, the flicker/waver on another nearby monitor is
- not entirely due to power fluctuations, but is more due to that "deep hum"
- operation. The degaussing field of the HP monitor is strong enough to
- cause some pretty major distortion of a monitor sitting next to it (just
- try pressing the "degauss" button without cycling power :-).
