I haven't been playing the panel lottery, I returned the PM because it seemed like a legit hardware issue going on with the speakers. However that PM display really started to bother me because I could swear the right side was dimmer or warmer than the left whenever I read text on it.Definitely seeing the brightness gradient, most Samsung screens have this issue. Are you planning on playing the lottery again for a new screen?
I really don't think I'm going to be happy if I go back for a better panel. I just can't believe this is what people call the "better" of the two manufacturers.
