I just bought a new LG LG 43UK6470PLC 43" with the intension of using an Xbox one X with it. Now I've seen loads of videos and tips on how to enable the full HDR for this by going into the settings general tab and having the option at the bottom. The only problem is the TV doesn't appear to have this? It's a full 4K HDR ultra HD TV and the new 2018 model, am I missing something? I've watched this guys YouTube video LG TV - Xbox One X - HDR & 4K FixWatch this video on YouTube But my TV does not have this option in the menu?
