    i just found out that ATV4K lacks support for 3D video. Has anyone heard anything from Apple on this?

    What do you mean?
    No Apple product so far has ever supported 3D video.
    If you mean SBS/OU pseudo-3D, then these are not 3D formats, they just fit both eye pictures into a single FHD frame. Hence no device in the chain thinks it is handling 3D signal and the final heavy-lifting is left to the screen.
    On Sony Bravias, pseudo-3D can not be turned on if input signal is UHD. So you must switch your aTV to output 1080p signal first, then 3D options become available.
    It is so by design. Check if your TV has same limitation.

    If you use VLC or some other app tp play a 3D movie then you see the side by side or top-bottom picture. However, the TV refuses to understand that it is a 3D image. I have discussed this with Firecore regarding their Infuse 5 program. They say the problem is that ATV4K is incapable of passing the 3D metadata to the TV. Much like ATV4K not being able to pass Atmos or Roku not passing Dolby Vision, it is a limitation of ATV4K. ATV4K has more than enough capability to play 3D. If Roku can do it and nVidia's box can do it then ATV4K is capable of doing it.

    I learned that I have to switch from 4K back to 1080, then the TV gives the 3D option again, otherwise it is grayed out, as there is no 4K 3d content.

    But then surely you just got into the TVs 3D setting and manually select SBS or top-bottom?
    That’s exactly what I do with 3D content on YouTube.
    My Panasonic however won’t let you use 3D while the TV is set to 4K so have to change to 1080p to be able to enable it.

    Manual selection of 3D isn't available and AUTO doesn't work. I'll check on forcing 1080 on the ATV4K although that sure is a pain. The material is 1080 so you would think ATV4K would switch itself. If I platy the files off of the Oppo 20 3 then 3D works. If I play off of the TV's FILE app then 3D works. However, I like the subtitle options on VLC and Infuse.

    Thanks. I'll try this.

    TV4K doesn’t have Auto Resolution switching so everything 1080p and under is output as a 4K upscale.

    That is what I tried to say by "it is so by design". UHD standard ditched the 3D picture, so most UHD screens will not switch to SBS (Side-by-side) or OU (Over-Under) pseudo-3D mode, if you send it a UHD (2160p) signal.
    You need to manually set aTV 4K to output 1080p picture, then 3D options will become ungreyed.
    If, like Gonzo said above, aTV would have also resolution auto-switching, it would not be a problem. Current tvOS upscales everything into output format set in its audio&video settings.
    Sorry, if my message was not understandable.

    It took a bit of experimenting but I got it to work thank s to your comment and those of others. I had to not only switch to 1080P but to SDR. Then the TV went into 3D mode. It's a pain but it works. Thanks everyone.

    I keep my aTV 4K at SDR output at all times and have enabled the automatic range switching. This way my TV is in SDR mode until I really play a HDR media.
