Hello all!
Recently finally got a 4K HDR TV to go with my Apple TV 4K.
As far as I can tell, neither the Apple TV 4K's Movies app nor macOS's AppleTV app ever download the 4K media for local storage, but they always stream from Apple's servers. Does anyone know of any documentation on this, and how the bitrate is determined? On iOS I see the file sizes for downloads for HD and below, but not 4K. On macOS, I see only HD as download option, and only streaming options for 4K (I was hoping to use Home Sharing from my mac perhaps).
I'm looking at getting the absolute maximum image quality, and when streaming from other services I've noticed some artifacting (color banding in gradients) that I think are related to the encoding and/or bitrate.
Thanks for any info! Google or ChatGPT did not help me much (I think mostly because '4K' is in the product name).
Like many, I was not getting the best picture quality I was expecting from my 4K AppleTV on my 4K TV, until I finally found these settings.
On my AppleTV I have the following settings:
Format 4K SDR
HDMI Output YCbCR
Chroma 4:4:4
Match Content:
Match Dynamic Range ON
Match Frame Rate ON
These settings finally allow me to watch content in full 4K (3840 X 2160)
I hope this helps you.
So don’t enable Dolby Vision?
I think having match content turned on will enable Dolby vision when it is available.
