I just got the Apple LED display and I noticed that when I put my UBMP to sleep or shut it down, the Apple LED monitor has a high pitched buzzing on the lower left corner. My dell also has a high pitched whining noise when it went into standby BUT at least I could shut it off. There's no button to shut off the Apple display. Is this normal? Can anyone confirm there's a buzz on theirs? (remember, the UBMP has to be either in sleep or shutdown mode). This is very very disappointing. Also, when I type, the monitor shakes. I have a very good sturdy business desk. My previous Dell 2707WFP monitor NEVER shook, the apple monitor is shaking horribly. If this is the quality of Apple, I'm definitely going back to PC.
