My LCD monitor (now long out of production) was indeed a lot less noisy than
the old CRT model. My LCD screen came with a small switching 12 volt power
supply, though, and it generated a lot of hash by itself. I finally
replaced the little switcher with a linear (non switching) power supply to
cure that contribution to noise. The only noise now coming from the monitor
is from the video signal coming from the video wiring and there is nothing
to be done about that but it occurs only here and there in the spectrum and
is rarely a problem.
I would predict that most LCD monitors are far less noisy than the old CRTs
but be prepared to deal with the broadband switcher noise from the cheap
little power supplies that come with the new monitors.

difference!
I have been considering a switch to an LCD monitor, but since finances
will lead me to buying the cheapest thing I can find, I have hesitated. I
would like to hear any 'specific' models/manufactures pros and cons for
19" LCD's other use.
