I got a new LED panel (Dell's 1080p B+RGLED) and it is great as far as color goes. Blacks are also very dark.
However, the center 1/3 to 1/2 of the screen at the both the top and bottom edges has a slightly brighter black. It is only noticable when the screen is covered entirely in a black image. It's not exactly "flashlighting" that I've seen elsewhere, as that tends to be very prominent. This is a barely noticable glow, along the top and bottom edges, slightly less visible on the top edge.
I tried to take a photo to illustrate the issue, but because of the glossiness/reflection of the display, I've had issues. I'll try again with a better camera in a few days.
My real question is, is this a defect? I have noticed other LED panels with similar glows along different edges (my Toshiba laptop glows along the sides particularly, instead of the top/bottom).
I tried replacing it however the replacement was faulty. I am not entirely sure I want to mess with getting a third replacement.
It almost appears to be be a gradient. With the screen getting ever so slightly brighter as it reaches the bottom edge.
