Forgot to quote, this message is in response to AJ's question...
The higher frame rate in gaming is essential when panning quickly around the environment, usually to shoot something before it shoots you. It's difficult to resolve all the action with only 30fps. WRT the post already answering your question, I can attest to the higher frame rate mitigating some of an LCD panel's weaknesses like latency and motion resolution. On our TV a 30fps game doesn't look so hot; motion "looses resolution" and everything gets a bit flickery and blurry. On a game that runs at 60fps, however, those issues go away to a very large extent. It's night and day.
I'm playing infamous on ps4 fight right now and even with interpolation on it's a bit messy (30 fps). Call of Duty and Metro look pretty great (60 fps, game mode on, interpolation off); the motion blur is pretty minimal.
AJ, do you have a Darblet connected? I got one response when I asked a few pages ago and was hoping some others would weigh in. The PQ on this set is among the best I've seen. I'm wondering if the Darblet really does make a difference, and in what way is it noticeable? Being a gamer I'm also curious how much latency the extra processing adds.
My phone magically started working with the tv today. It wouldn't synch before. I threw a 4k video clip from YouTube onto the set and watched it: some nature footage. It looked incredible, but very well could have been just full hd. The display button didn't show me the resolution and the Android phone app didn't list it either. I suspect it wasn't 4k, but my God, some shots were jaw dropping nonetheless.
