that monitor emissions are harmful, much effort has gone into reducing emissions on the
principle of better safe than sorry. Currently, there are two areas of interest: very-low frequency
(VLF) electric and magnetic fields extending from 2 kHz to 400 kHz, and extreme low frequency
(ELF) fields extending from 5 Hz to 2 kHz.

Moiré effect
A fringe pattern arising from the interference between two superimposed line patterns.
In a monitor it comes from the interference between the shadow mask pattern and the video
information (video moiré), and between the shadow mask pattern and the horizontal line pattern
(scan moiré). It shows itself as wavy patterns on the screen and becomes more noticeable as
monitor resolution increases. Since the video signal varies continuously, little can be done about
video moiré. Scan moiré depends on the horizontal scanning frequency and can be alleviated by
appropriate choice of frequency. Autoscan (MultiSync) monitors, which operate over a range of
scanning frequencies, may sometimes exhibit moiré in certain video modes.

The feature that allows an end user to adjust screen performance and parameters of monitors
directly through an on-screen instruction window. See CustoMax in CrystalClear section.
