Samsung 65-inch curved gray strip showing near display. The TV is just days past the one year mark
So, I don't think it was the polarizer. Maybe the picture doesn't do it justice but there isn't any de-lamination going on. To me it looked like some sort of adhesive strip was coming up from between the bezel and screen and it wasn't attached to the screen (I could put my nail behind it and it lifted away from the screen with no resistance. I'm not sure if this strip is maybe some cushion between the bezel and screen to prevent rubbing or whatever it is. BUT, I did try to push it back down into the bezel which it really didn't want to stay down and I ended up knicking the bottom of the actual LED panel causing a fracture from top to bottom. So anyone reading this with this don't try pushing it back down maybe just live with it it wasn't that bad. Also Walmart has good deals on new tv's right now so I am now a new owner of a Phillips TV.
Nothing but a very lightly damp microfiber towel was ever used on the screen. My cat likes to leave paw prints on the screen so the water made it little easier to get whatever grime he left behind off.
