My ks8000 seems to be forcing some level of motion smoothing. I have all settings for it turned off and have had this tv since 2016. This seems to have started happening since the last time I updated it.
If I enable game mode it stops and looks normal. But with game mode off using movie or even standard preset with all motion smoothing turned off it's forcing it. I've tried Blu-ray's, UHD Blu-ray's, streaming, movie files on PC, does it to everything.
It's not the full soap opera effect but can tell it's doing some level of light smoothing and its very irritating that it never did that for years but now I have to watch movies in game mode which doesn't look right.
