Armogeddon00 had this to say gah my monitor is making a humming noise thats a first, any 1 else have this prob, it goes away wen i turn it off but its pretty annoying
Check your grounding. Also, try turning off all other electrical devices on that circuit (TV's, Stereo, Clocks, Phones, etc). You may be getting interference from something.
An overloaded capacitor can hum, usually a sign that something is failing. (As t1 found out... )
...maybe it hums because it doesn't know the words...(someone had to do it...)
You could just try fooling around with the different available refresh rates, and see if that helps, wouldnt hurt any. But what could also be a problem is if there are any speakers near by, like profdlp said.
after searching around my computer desk with the wires and the cords i got under it to check all my connections into the surge supressor i have adn thats whats making the noise, its like humming and vibrating making the noise i was describing, i unplug the monitor from the surge and plug it into the wall and the humming is nearly gone, that dosnt make much sense to me
this is my surge
its a belkin isolator surge protector model F5c980

Transformers sometimes hum and vibrate.
I'm not quite clear... is it the MONITOR that's making the noise, or is it the surge protector itself?
the surge protector, i thought it was the monitor because when i tunred it off the humming would stop, so im thing "great my monitor is going to blow up" then Disvengeance said to check the cables and the surrounding wires for emi or some other kind of interferance, when i got under my table there was my surge protector humming, so i unpluged the monitor from it and the humming has decreased 10 fold
thats 1 ur describing is the 1 i got =) i could only find that pic its only about 4 months, i got it after the hurricane isabel fee-asko

I'd e-mail Belkin and ask them. It sounds to me like you have a bad surge protector...
Normally, I'd say just replace it, but those damn things are expensive... mine was like $75, and I assume you paid about the same (unless you bought it online or something... I got mine at officemax)
Seems like the surge protector is overloaded. But at the quality of surge protector you bought, it shouldn't overload with what you've got on there, even with the monitor. Do both the "grounded" and "protected" lights still light up solid when the monitor is plugged in? What kind of warranty is on that thing? It's new enough it should still be covered.

Surge protector isn't overloaded, that much I can guarantee, even without seeing it. I've got the same one he does, and I power all 4 comps, my router, dsl modem, 21" monitor, 35a/15v bench ps, 120w THX 4.1 speakers, 30w 2.1 speakers, a 12x12 wacom tablet, and a Palm cradle off mine, and it hasn't got this problem.
If there's a fault, or something goes inside the unit, one or both of the lights may go out. For instance, since I've only got 2 outlets in my bedroom, and one runs just about all my PC stuff, the "protected" light stays off on my desktop surge protector if I plug in a CRT monitor (LCD it's OK), and the "protected" light on the surge protector in the wall flickers constantly while the PC is on. Not good, but I can't change it until I move out of the parents' house...

To be honest, those things do have a limit on how much they can handle, each. If you have everything plugged into one surge protector, that could be a problem if you are drawing over the nuber of watts it is rated for, probably on a sticker on its underside. In this case, it will also last longer if you take soem of the load off of it, as happened with the hum decreasing when you took the monitor out of the circuit. One way to handle is to get a second surge suppressor, maybe not a best line Belkin, plug the less expensive gear into that, then plug the monitor and main computer box into the more expensive one. I think the problem is load related, drawing more through it than it is designed to protect, or it is handling a long term but not high surge overvoltage situation.
Plug a lesser quality surge strip into the other outlet, run more minor gear on that, please, and no laser printers plus whole computer printers on one strip-- reason is that lasers can grab all the wattage a good strip can provide all by themselves.
Real good Belkins are power conditioners, really, and can have transformers in them, and transformers can make noise like that. A marginally poor ground at outlet can cause this also (not no ground, just an outlet that is kinda old with crystallized copper or brass contacts inside, will give some resistance and that backed up wattage will feed back into the surge strip until resistance is overcome, and cause any transformers to feedback hum).

I've got almost the identical model (mine's black, doesn't have the coax protection), and I haven't had the problem you're describing.
