Hot on the heels of iOS 11.2, Apple has just released tvOS 11.2 for the fourth-gen Apple TV and Apple TV 4K, as noted by 9to5Mac.
The update fixes one of the biggest issues with the Apple TV 4K by adding content-matching options for video. Specifically, the Apple TV 4K can now be set to Match Dynamic Range, which will “play content in its original dynamic range” instead of forcibly upscaling content to HDR; and Match Frame Rate, which will “play film and international content at its original frame rate.”
