Summary: Picture is nice. Sound is a lacking. I will end up buying a sound bar to go along with this. We use Netflix 80% of the time and one thing that is VERY annoying is black flashing while watching any content. It may occur a few times a minute or once every 30 minutes. It varies. From research I've done this happens when the video streaming mode changes.
Summary: Bought this tv a few weeks ago. The picture is fantastic after tweaking the picture settings! The blacks are great for an LED lit tv and not much of a flashight effect that you get with some LED tvs. The sound is not bad at all as long as you max out the bass (+15) and turn bass boost on. I also have a sound bar and use that most of the time but can't complain about the sound of the TV. I have xbox 360 hooked up to the TV and see no issue when gaming.
