I just got a new 4k box. I adjusted the settings to UHD 4k. I think Xfinity > Settings > 4k setting (highest 4k setting)
1) Will Xfinity Auto tune to 4k if its being broadcasted live?
2) Do i have to go to the channels in 1000s to access 4k programming?
3) Can you access live 4k programming via Xfinity stream?
