Re: Acer LCD Making Noise. :/
Well, I had a similar problem, but it was on my laptop, believe it or not.
Whenever the brightness was set anywhere above... Around 40% of the max, the screen went entirely white when most of the screen was supposed to be white, and after about 20 seconds, or so, there was a really annoying sound... Although it was not at all loud.
This was on my Toshiba Satellite, and they just replaced the system (they asked me first, so I could get any important files, that kinda thing)... I'm not sure if Acer would replace your monitor...
