Hello
I checked my friend model its 55UB NOT 55UF. UF is better. I went to LG to check other TV because I thought just my TV has the problem, but It's not. Also the store TV has the same problem !! I checked the 49,55 there is NO TruMotion. There is TruMotion in 65 only. I told LG service I don't want this TV anymore. And they contact the manager to checl this problem and they still confused about the problem.
I'm still looking for solution.
