Viewing data for Noisy Screen

Comments: I just bought and received a new 21.5'' iMac and love it but the screen is making a high pitched noise, similar to a dog whistle. It's that sound that isn't loud but pierces through your brain. And the brighter the backlight is, the louder it gets.

Specs: 21.5" 3.06 Core2Duo 1TB
