tvOS 16.4 adds a feature called “Dim Flashing Lights.” It’s an accessibility option to automatically dim the display of video when flashes of light or strobe effects are detected.
In Settings on Apple TV, go to Accessibility > Motion, then do any of the following:
- Reduce the amount of motion displayed by Apple TV during navigation: Turn on Reduce Motion.
- Automatically dim video content that depicts flashing or strobing lights: Turn on Dim Flashing Lights. When this feature is enabled, the playback timeline indicates when flashing lights occur for supported media.
Important: Your Apple TV uses an on-device algorithm to detect flashing or strobing lights included in supported video content and automatically dims them on your TV in real time. Motion settings should not be relied upon in circumstances where you could be harmed or injured, in high-risk situations, or for the treatment of any medical condition. - Turn off automatic playback of video previews: Turn off Auto-Play Video Previews.
(This how-to is based on my experiences and info on Apple’s support pages.)
