Hey guys, I've basically been going insane trying to decide what TV to buy and if anyone could lend a hand it would be greatly appreciated. I'm looking to buy a 4K TV, mainly for gaming (PS4 Pro, online FPS, sports games, RPGs, etc.) and watching Netflix and Sports in Ultra HD. Must haves include: 4K, bigger than 49", low lag for gaming, must be less than 1000 pounds. Things I don't care about: sound quality, 3D, curved, stand design as it will be mounted on the wall. As I'm over in Italy, choices are a little bit more restricted, but I've narrowed it down to three: Samsung 55" UE55KU6400 at 699.99 Samsung 49" UE49KS7000U at 959.00 Sony 55" KD55XD8005B at 999.99 Ideally, I'd like at least a 55" but very undecided if the quality of the 49" Samsung is worth it considering the jump in price. (Is the KS series that much better than the KU series?) Same, with the Sony; is the quality good enough to justify the significant price difference, particularly because the Samsungs only offer 60hz. (And should the refresh rate even matter, 60hz or 120hz?) If you can give me any idea which would be best, or have any other left-field suggestions I'd really appreciate it! Thanks in advance!
