    So I noticed that every so often while watching my AppleTV on my 4K Vizio TV I get this green pixel looking screen and then it goes away. Wondering what it could be. I have my AppleTV going through my Onkyo receiver to the TV. I also have my XBOX going the same way and there is no green flicker. So I am thinking its either a HDMI cable or the AppleTV. Thoughts?

    Do the cheap first.
    Swap cables, between the worker and suspect device. Feed the Apple TV direct for a while and see if it is the amp.

    Try another TV input.

    (Edit, one is assuming you are using the correct cables for 4k and that the xbox is providing a 4k signal).

    I had a similar issue right after I got my first Apple TV 4K with my 65" Sony 4K HDR TV. Fixed the issue by replacing the HDMI cable with a better quality one.
