Faulty Laptop Screen???

Hi everyone. This is my first post. I've been lurking for some time and have found the forums very interesting. Here is my situation:

I recently purchased an off-lease Dell D610 laptop only to find it had a white depression mark in the middle of the screen. I have since had the screen replaced by the seller; however, I'm not certain the new screen is up to snuff either.

Apart from a few stuck pixels (which I can live with) the laptop is like new. Unfortunately, my main complaint is that the screen also has a slightly dim border approx 2" in width all the way around.

All images are still visible and bright. The border is simply "less bright" when compared to the rest of the screen -- almost like the white reflective backing has started to bend and lose contact with the rest of the LCD display. This "border" does not have a straight edge; instead, it seems to meander a bit, but the edge is definitely well defined. It is also more visible when displaying solid dark colours.

Anyone have any experience with this. Is it fixable?
