I'm looking to get the Sony 75" Model KDL75W850C. My question is. For years I was always concerned about an LED TV that has less than 240Hz but now I'm hearing that most of these 1080P and 4K TV's are 120Hz and supposedly it's because the other technology around the TV makes 120Hz more acceptable and much improved than it did years ago. Not sure if this is true, maybe someone here can tell me if I'm hearing correctly. Also, the sales guy told me that Sony's Xr 960 processor with this TV model is what makes it's 120Hz better. I always thought 120Hz is 120Hz... didn't know other things can improve upon this which shows what I know. Can someone verify or break down if this is true or not and why or why not?
