Is this screen issue normal?

[g.costanza]

If I watch "full screen" video in landscape mode with the top of the screen on the left, I see a thin, faint vertical line very close to the left edge of the screen. Right side (bottom of screen in portrait mode) has no line. The line is a little lighter in brightness and causes video passing over it to be slightly distorted. I went to best buy, where I bought it and both display nexus 7's seemed to have the same line, to a slight lesser extent. Do you see the line on yours? It's maybe 1mm wide and about 1mm out from the left edge. Again, in landscape mode with top of screen on left.
