Some settings I changed it to, a while ago, said to put it on 66. Well, if you watch F is For Family, on Netflix, certain scenes will be flashing, like the wall. I first tried turning the backlight down, then the brightness, got to sharpening, and setting it to 30 or 20, got rid of the flashing.
Didn't notice that on South Park, on Philo. Even pausing the show, it was still flashing. The walls were flashing, like a flickering light. I don't think the show is supposed to be like that, considering decreasing a setting got rid of it.
