Summary: Don't buy this. I've had one for less than 2 years and its already broken. I didn't even use it very often. My primary TV is a Vizio, supposedly a less quality product, that I keep in my bedroom and has lasted wonderfully for over 5 yrs. The Samsung, I used maybe twice a month and so with probably less than a couple hundred hours of use on it has already failed.
Summary: I purchased this set about 18 months ago and now the TV will not power on anymore. I called Samsung and they will not back up there product. Its going to cost me $250 to repair. My Sony lasted over 10 years. I will never buy another Samsung product again! It doesn't even deserve 1 star.
Summary: I have this TV in my sunroom and I generally watch at night. Watched 3D stuff through VUDU trailers and it is great. This is a 2012 model which can use the new and lighter 3d glasses. 720p - Unless you watch tv at a distance of less than 10 feet, 1080p or 720p does not matter. I connected the tv to my sony bluray player with wifi and love it. Channels on my cable look great. Took couple of days to adjust to the size but like it now.
