I been given on free loan from work an 19'Iiyama Vision Master Pro 454, now that we have switched over to TFT's.
While I probably wouldn't (after a recent experience with another 19' CRT) have brought a CRT monitor myself, I was in the market for a larger screen (than my current 15' inch TAFT) and I certainly can't argue with the price!
However by dint of the fact that my base unit is in another room connected by long cable runs to my home office I have a very quiet (when I want it to be anyhow)home working environment.
I've noticed that the monitors makes a humming noise that while not loud is just enough to be distracting and it seems to vary in pitch depending on the refresh rate selected-currently 90 MHz at 1280x1024. My question then is this normal?and if so what is the cause of this noise since I seem to remember reading somewhere that it can be the result of coil whine.
I emailed IIyama and while they were unable to resolve the problem with the monitor they have offered to replace it!
I'm going to have a word at work (since they often offer to sell off old IT stock to staff) and see if they will sell me it.
If so once its mine, I'll get it replaced, otherwise I'll take it back to Work since to replace something that isn't mine is not really on and the buzzing while less pronounced than it was is still there.
High Tension, it is the Transformer that produces the HT volts about 35.000volt in a colour TV or Monitor, that create the picture on screen sometimes it's high pitched whistle, something I do not hear now days with hearing aid
