I just brought home my Samsung PN50C700 last night. I thought everything was good, then when I was running some break in slides I saw that the pixels were not all the way over to the left side of the screen, up next to the bezel as they are on the right. I thought it was how my picture was set, but soon realized it was nothing like that.
I took some pics with the set off, because you can see it pretty good that way. The first 3 are of the left side, you can see how the pixels do not reach all the way to the bezel. There is a black void where the pixels end and where the bezel is. The 4th is of the right were the pixels do reach the bezel.
To top it off, that black void on the left side is wider at the top of the screen then tapers toward the bottom.
