U2410, Screen Wrinkles?

I have three 24" Dell Ultrasharp displays in a row and a 46" Insignia LCD TV above them. My left-most display, a Dell U2410, has some wavy areas where it's dark. It's not super noticeable at all times, but when that part of the screen is showing a mid-tone solid color, it become very apparent.

I don't believe the display is still under warranty, though I'm not sure. If it is, I'd like to know how to go about getting it exchanged. If it isn't, I'd like to know where I can find more information on repairing this issue myself.

I've attached an image illustrating the issue...

* Was the monitor purchased directly from Dell or some reseller? And when?
Not sure, I have two U2410s and one U2415. I believe one of the U2410s was purchased from Dell and the other was Refurbished through Dell but available from a third party on Amazon. Don't remember exactly and don't know which is which.
