In case you didn't do it already: run "getedid delete"and reboot
That did the trick and it showed up immediately once I did that and a reboot!!
So question, will this option make a difference for me? Will it be better in terms of just upscaling lower content than 1080p? And 10bit files will play at a lower chroma level of 4.2.2? I just care about it looking the best as it possibly can on my 4K TV. I don't care about playing any 4K content obviously.
Thank you guys.
