Hi Josef,

Perhaps it is a "Moire" pattern adjuster.. basically when you get stipple
patterns (alternating light and dark checkerboards like in a windows scroll
bar), some times this overlays onto the internal pixel mask of the monitor
and results in an optical effect that can produce "wavy colours and lines".

This is difficult to explain.. and I think that is how it works.

If you're using the standard (grey) windows colour set, it is most apparent
in the scroll bar.. try adjusting it when looking at a scroll bar.

Cheers,
Ash (who spends about 10 minutes setting up a new monitor to be "perfect")
