Samsung 4K UHD JU6700. Samsung's usually have 2 ways to get rid of latency. Disable all things FIRST, then turn on game mode. For HDMI1, usually it's a simple case of setting the name to DVI-PC and that way there you get Chroma 4k @ 60hz with no post processing. For my PS4 in HDMI2 I needed to do the first, then set the name description to game and I was able to play Rocket League flawlessly (not like PC though, cause 250fps > 60).
