YCbCr 4:4:4 vs 4:2:0 (Help needed)

[stackerboy99]

Hello,
I currently own a Panasonic UB820 4K Blu-ray player with a Samsung NU6900 4K TV. What 4K/60p Output setting is recommended for playback of the three formats (4K UHD, Blu-ray, DVD)? Setting is on the player.

Available to choose from are:
-4:4:4 (4:4:4/8bit or 4:2:2/12bit)
-4:2:0 (4:2:0/8bit)

If anyone is also able to tell me the difference between the two settings, that’ll help as well.

Thanks,
Dan
