tvOS 15, Apple TV 4K 2021, and HDMI 2.1 bandwidth.

  1. The hardware in the 2021 Apple TV4K can support bandwidth of 48Gbps provided by the HDMI 2.1 spec, but atm eArc is the only feature that differentiates the Apple TV’s. Right now more features are only speculations and we just have to wait and see what Apple decides to add. None of the features you are looking for has been added yet.

  2. Thank you for the reply. I hope they do it soon; 120Hz support/increased bandwidth is the primary reason I was so excited for this new Apple TV. The new remote is great, but man do I want to leave the black screen behind.
