I just got mine last Friday. Very happy with it! Things to note:
-very faint white vertical lines on pure black background (very minor)
-had some audio sync issues that went away after factory reset. The newest firmware was the first thing I installed when I opened the box, so I can't say if that made it any different compared to stock firmware. I use game mode for every device, and every single picture option turned off.
-I don't like how it drops the backlight when screens turns pure black, because it takes a split second to light it back up. No way to turn that off - but I do have the backlight set to the lowest, so the change is very minor
-The worst sound I have ever heard from a television. The speakers also point down, causing more psychoacoustic delay from the image, and it messes with your head. Just terrible.
-amazingly low input lag on game mode - the best I've ever felt
-power consumption of 202w with the way I have it configured - very good for the size!
Overall I'm very happy with it.
