I am using an NEC MultiSync 70 monitor (17".) I find it to be very quiet.
I had the same results with the C500 15" NEC monitor as well....my wife is
now using that one in her office.
If any of you ever have the chance to take the cover off of an NEC monitor
you will see a great deal of shielding. Compared to other 'bargain'
monitors out there, there is a very real difference in shielding. Once
again, it is an instance of getting what you pay for......
