Apple released tvOS 11.2 for the fourth generation Apple TV and Apple TV 4K on Monday. They update adds in new frame rate settings for HDR content.
Apple TV 4K users can now set HDR video to play at its original frame rate, effectively turning off the dynamic frame rate changes the device was previously imposing. The update also adds ESPN live sports support to both Apple TV models.
tvOS updates automatically install on a preset schedule. If that’s not fast enough for you, open the Settings app on your Apple TV, then go to System > Software Updates to force tvOS 11.2 to install immediately.
