    Recently I've been getting a black screen & lag when starting videos on my Apple TV 4k 64 gb. It's frustrating. I don't know if it has to do with HDR settings?

    Maybe a recent update broke something?

    Anyone else having this issue?

    If you've activated either HDR or framerate adaptation, then this initial blackout is what you will get.
    And it is the display, not the aTV, that takes time to adapt to incoming stream.
    For most movies the display framerate switch is inevitable, because aTV UI runs at 50/60fps. Majority of movies do not.
    Some of them do it faster than others.
    That was also the reason why Apple initally called these display mode switches as inelegant from UX point of view.

    The section at the bottom (learn more) mentions the black screen/flickering. I was perplexed about this to start with. Can’t give you any tech reasons, but maybe the answer is to accept it to achieve the best video experience - I dunno! Depends on what you are watching I guess.

    If switching the aTV back to fixed output (not adaptive) does not solve it, then I would look into a) HDMI cable b) aTV device and c) TV/display in that order (in order of increasing cost of replacement).

    Like said above this is your tv or monitor switching to the format of the source material. This is happening because of the tv or monitor not the Apple TV.

    If you want it to stop turn off match frame rate and your Apple TV will no longer play the source material in its unaltered state and instead play it at the tv / monitors refresh rate and the black outs and lag will stop. However the material will always look better in its native frame rate and I mean much better. Some TVs are better then others in the format switch and speed that they do it.
