Should I be concerned?

[ChroniC]

I bought a Dell Ultrasharp u2711, and I love it, however I have noticed something and I don't know if it is common or a problem waiting to happen.

I work with editing photos all day long, and have a lot open in Photoshop, and have noticed that the ones open to the edge of the screen have a noticeably lower contrast and saturation.

Is there always such a fall off around the edges or is this a ticking timebomb?
Ive tried googling it but have been unsuccessful.

Could just be uniformity variations from the backlight. Unless you use it for a lot of hours it shouldn't get too bad but if it does and becomes an issue you may want to look at a replacement
