Have you tried changing up the Auto Motion plus settings? These should be found in the picture menu. I would try that to see if it helps clear this up.
hello - i recently got a samsung 4k tv, un55ju6400. there is significant motion blur on my directv programming. directv cant seem to offer a solution other than to keep selling me upgraded receivers and packages. any settings i can change? do i have to have the 4k content package from directv even just to watch normal hd channels? i have the hr54 receiver with the 4k genie mini connected.
