Hung the new Samsung and realized 4" of the right side margin is black, crap. Didn't notice until I had cut the giant cardboard box up. Pulled it down, taped the jig saw puzzle of a box back together, loaded the giant thing back up and waited in a 45 minute return line at Walmart. Ugh. Bought a 75" TCL. Hung it on the wall and so far, so good. What an ordeal, thanks Samsung. I think the picture is actually a little better on the TCL.
