The 11.3 Update Now Includes Frame Rate Matching
As previously only available to Apple TV 4K owners. Frame matching is now available on all Apple TVs (4th Gen and 4K). An altogether small and modest update but keep in mind that no jailbreak is available for tvOS 11.3 and it is available to max tvOS 11.1. So stay tuned for the go ahead to update.
