I've now had the set for about a month, and I'm still very happy with it. The only thing that gave me fits was getting the ARC to work right, but that was user error more than anything else. Now I can use the built-in apps and send the audio back to my receiver with no issues. It's funny I went through all that work and I'm not using the "Smart" features anyhow. I should have known better.
I love the fact that I have over a dozen pairs of glasses, and I had the neighbor's family over the other night and watched How to Train Your Dragon 3D with plenty of glasses for everyone to enjoy it. I replaced an active Sony that I still only had 4 pairs of glasses for 2 years later.
Picture wise, I'd like a little deeper blacks, but know this isn't a plasma. The picture on my Sony 40HX800 is a little superior, but not all that much. The picture on this set just isn't quite as sharp. I don't seem to have any flashlighting issues, but I do notice the dirty screen effect when there is no signal. It completely disappears once there's actually content.
Overall, I'm very happy with this set and would recommend it.
