So My 60 inch lcd broke. its 7 years old so I decided to buy a new tv. I am looking at a 50 inch models. Its been so long since i bought one can anyone recommend one for me that is a 50 incher 1080p . i know the input lag needs to be low. Are 4k tv's worth it when games on ps4 and x1 arn't even in 4k yet? how do 4k's handle non 4k pictures? Iv been looking online but there are so many mixed opinions about the same tv's. Thanks guys
