Due a smaler coulour band signal. The slow colour change
is a real pain for movies but the 50 vs 60 Hz isn't
visible, althrugh when used with computers, both are
just bad.

Al long as you are using an RGB monitor, almost any will
syncronize well. For FBASthere is a problem, but most
actual TV sets should display PAL and NTSC (and 50/60 Hz)
without any doubt. Timing isn't any longer generated from
the power line. Also, since most TV controllers are IC
based, they use just one type everywhere.

This might not be true for the low price TV sets, but
any TV I (or friends of mine) had within the last
10 years could syncronize 60 Hz b&w and all (but one
tested in 1984) could also display NTSC signals.
