I'm still using tube monitors. For LCD the refreshing rate doesn't
matter, because the screen will be refreshed, but without going out. For
a tube monitor it's going out and refreshed, this does cause the
stroboscope effect.
However, some people are sensitive and even the colors could cause pain.
I like to kill all the politicians of the EU, I only own 7 auxiliary
reflector "small heating device", when they die, I'm forced to use
energy saving lamps, degassing plastic and incomplete light spectrum
with evil peaks for the spectrum will cause sickness. Btw. the
durability for a reflector lamp is some month, but for a reflector
energy saving lamp some hours, max some days only. YMMV!
Perhaps it's for some or all LCD displays similar. The angle of vision,
colors etc. all this in combination in the sum might cause problems for
some people.
An artist I know had no health issues using a LCD display, but even an
expensive, modern LCD display doesn't show the same color, if you
minimal watch it by another angle of vision and it's impossible to keep
the same angle of vision. He doesn't use the LCD and use his old
monitors again.
New isn't always better!
