Yeah, just measured and its more towards 1cm. Sorry, I remember taking a measurement before, but I forgot I was only measuring the black boarder around the panel rather than the thicker part of the plastic.According to the RTINGS review it is actually 1cm.

The 3rd one however is really bad with a bright leak coming from the bottom edge about 2 inches in from the right edge. Now on majority of backgrounds I don't notice it but as soon as you go black you can and of course like a blemish on anything once you can see you can't unsee it and you will always look for it. The problem is really noticeable when watching a 21:9 movie as the glow at the bottom is always noticeable.
