I'm thinking of buying a new 55'' Samsung KU7000.
I have a standard PS4 (not Pro) and I heard that some people are having problems with display/input lag on new TVs. I even know someone who bought Muller TV (unfortunately I don't know the exact model) and he can't play at all because of the lag!
I tried googling the KU7000 to see if there's any info of lag but couldn't find. Is this something common, for the old PS4 to lag on new, large TVs? Is the PS4 "working" harder in order on bigger TVs because the output is larger? Is there anything to do if there's lag, like changing the PS4 output preferences?
I just don't want to buy a new Tv and discover that the gaming experience is actually worse than now
