The next software update for the Apple TV 4K will give owners of the month-old set-top box a little more control over their video output settings.

As noted by MacRumors, a video released on Apple’s Developer site this week says that the Apple TV’s tvOS 11.2 update will allow the set-top box to automatically switch its display settings to match the native frame rate and dynamic range of a given video.
