LG UH6150, Xbox one s.
I 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)
I 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)
Do I need a 4k disk that contains calibration?
