LG UH6150, Xbox one s.\nI used the built in calibration on the Xbox to calibrate what it offered, basics such as brightness backlight contrast, I used the cinema mode on the lg. It made a decent difference and have no complaints (looking to possibly using something else, but for now I'm very pleased with it)\nI picked up my first 4k disk today, fifth element, and this is where my question starts. I started playing the movie and it looked wayyy too bright. I figured my 2yr old might have been playing with the remote so I checked the mode the tv was on. My cinema user is not an option, only a few preset uhd modes that thankfully I can edit. Question is, how do I get the uhd mode to edit? If I go back through with the Xbox calibration my tv only gives me the 'standard' display modes, the uhd modes are not available (only available when playing the 4k disk)\nDo I need a 4k disk that contains calibration?
