Bests & Worsts Reviews from Amazon

I've tried more than a few 49" Q80Ts from various vendors. #1 had two dead pixels that developed within a month. #2 had a quarter-sized welt on the screen, perhaps damage from shipping. #3 has vertical banding from DSE (the other sets were much cleaner). #4 was a keeper until it developed a dead pixel just slightly off-center overnight. The picture is gorgeous and bright, so it's the set I want, but the defects are disheartening. I'm currently using #3, the best of the worst, until I'm prepared to risk another purchase. 05/21/20 - I went through 6 of these things. All had at least 1 dead pixel. The last had over a dozen dead pixels. What's going on with Samsung?
