This is our first 4K tv, and the picture is not what we expected at all. Either to bright or to dark and dull, it's Very pixelated and blurry. I'm not one for calibrating so I don't know what to move and leave alone. So I just left it alone. It has preset pic modes, I keep flipping thru them and just when I think it looks okay, a different scene or commercial comes on and it's a mess again. GRANTED Timewarner cable doesn't offer 4K res yet. I have been using the Netflix on it, and streaming the 4K shows Netflix offers and thought this is really gonna look clear and pretty, NOPE! Same thing :/ I called Best Buy and they offered me to come in so they can hook up the same exact TV and see if my picture looks the same or different and then go from there. I'll update this when I have some answers. As for right now I can't recommend this with the way it currently is. ALSO SOUND, sucks def invest in a sound bar :) THE PICS I've posted actually look more clearer than in person, and are supposed to be 4K res thru Netflix
