For the Samsung J6300, what is the difference between the 50 inch and 55 inch you reviewed (besides size and price)? I want to know if the 50 inch version has the same 120hz that will work with 24p to stream video and if there's any reason the 50 inch picture won't have the same quality of viewing vs the 55 inch (other than size). I was looking for a 40 inch for my small living room but wanted the 24p video to stream without judder and I don't need 4k. So the JU6500 has judder and the J7100 is very expensive. The J6300 is a sweet spot and still for sale on Samsung's site and a few others. Thanks!
