Make sure HDMI Color Subsampling is enabled on the inputs in question.volvik wrote: ↑ Got mine this morning and hooked up as well. I have the Premium Netflix package for Ultra HD and am using Nvidia Shield to stream. I went for the Netflix Our Planet too but thought it would be better, when I hit the Info button on the Vizio remote it says 2160 Normal Dolby Audio at the top. I understand it should say HDR or HDR10 instead of Normal so I'm guessing I have missed a setting somewhere either in the Nvidia Shield or the TV.
Same issue I had with my Samsung KS when I got it and had to figure out how to turn it on.
