The 245T emits a constant buzzing sound from the upper back part of the screen. In a silent room, you can definitely hear it. Turning on MPA helps, but MPA makes the screen seem to vibrate.
I returned the original 245T that I bought to Samsung under warranty. They sent another one that had the *same exact problem*. I returned that one, and they sent another. *Same exact problem.*
That's 3 brand new Samsung 245T's with the same issue. This is obviously a flaw in the monitor that Samsung won't admit to, and can't do anything about.
Otherwise, the picture and performance of the monitor is great.
