Apple has released tvOS 11.2 for the fourth-gen Apple TV and the 4K Apple TV. The update includes a new setting for the 4K Apple TV that changes the HDR and the frame rate dynamically depending on the content.
The new ‘Match Content’ option is located in the Video and Audio section of the tvOS settings in 4K Apple TV. Under this option, users will find two more options: Match Dynamic Range and Match Frame Rate. The former ensures that all videos are played back in their original dynamic range, while the latter ensures that films are played back in their original frame rate.
Apart from this, the update also brings a new Sports section to the dedicated TV app which provides access to live sports games from within the ESPN app.
You can download the tvOS 11.2 update on your Apple TV 4K and the fourth-generation Apple TV by going to System -> Software Update.
