Hi - i am looking for a recommendation for a 4k 49" TV. I have been advised to look at Sony & Samsung (not curved). I have seen the following models in Curry's (Samsung 49KU6470, Sony 49XD8077 & Sony 49XD8305) which are more than my budget but if somebody could convince me they are worth it i would part with the extra cash. I would use the TV for my PS4 and mainly watching Sport/Movies. Any recommendations would be gratefully received!!
