Owners of the Dell 3008wfp, I just got this monitor and while it has amazing quality and picture, I seem to be getting a high frequency whine buzz coming from the back of the display. It's fairly faint, but noticeable since my room is very quiet and I'm very sensitive to high frequency sounds. Is this caused by the fan or other internal components? Does it go away after breaking in the monitor or should I get it exchanged?
