Sound from monitor speakers distorted and high-pitched
The audio from my Polyview LCD monitor is distorted. Everything comes out high-pitched. I don't know if this is a problem with the speakers in the monitor, my computer, or if some weird setting got switched on somehow.

Re: Sound from monitor speakers distorted and...
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!

A high-pitch squeal is common in CRT TV sets and monitors. I've never run across this in an LCD monitor, but there's a first time for everything. If the sound isn't coming through built-in speakers (if this model has them) and is being caused by the computer, I would suspect the inverter circuitry. This provides power for the backlight, and there are transformers that may have become noisy. Because of their construction, it's possible for them to vibrate internally, and at a frequency that you hear as the high-pitched noise. There isn't a lot you can do to quiet them. When I worked on TV sets, I had mixed success using hot-melt glue to muffle the noise, but usually the only way to completely cure the problem was to replace the parts. It's unlikely you'll find the parts available for a monitor, so all I can suggest is to bear with the noise as long as the monitor is otherwise working properly. Or use this as an excuse to buy a new LCD monitor; they are quite reasonably priced these days.
Yes this monitor has a built in speaker on it, here is the complete details about this monitor.<br /><a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16824024506&SortField=0&SummaryType=0&PageSize=10&SelectedRating=-1&VideoOnlyMark=False&IsFeedbackTab=true#scrollFullInfo">http://www.newegg.com/Product/Product.aspx?Item=N82E16824024506&SortField=0&SummaryType=0&PageSize=10&SelectedRating=-1&VideoOnlyMark=False&IsFeedbackTab=true#scrollFullInfo</a><br /><br />
hmm the monitor is connecting to the pc sound card ...and for that you have to have a sound driver installed...if you know what kinda pc you have its easy ..but if its a built one ..you gonna either look inside to see what is the sound card name ...or try to see if you have a previous sound driver installation .....if you did had sound or still have on the ear pieces you have to have on the monitor too..just see the volume ...and the cable connection ..if it has a separate one (3.2 jack )or it connects directly with a HD cable
I'd guess there is a jack socket 'audio in' somewhere on the montitor, probably on the back. (Don't confuse it with the headphone socket, which usually looks the same.) Connect it with a 3,5" stereo jack-jack cable to your PC's audio output.
There is no sound driver, they are speakers, they work off of the audio output jack on the back of your PC, on the motherboard. If you have the sound drivers installed for the motherboard, and no sound, then you have plugged the monitor audio cable into the wrong jack on the PC, or you have the settings wrong just as MIKE said above.
