I thought Samsung TV's nowadays have some kind of Game Mode, which is actually very good (can't remember what it's called, this feature). Unfortunately it doesn't work with Freesync at the same time, so you have to choose one or the other. But from one of the reviews I heard it's a tough choice to make (not in favor of freesync). Not done a full research though.I have a 1440p Freesync Monitor, might have a look at a Freesync 4K HDR TV though, afaik only Samsung make them currently?
