If you’re going to buy an Apple TV don’t get anything other than the 4K version (or if a new one is announced that’s faster by the time you purchase) The 4K does far better with the x265 compression, it’s faster processor makes the menu navigation better and many other pluses.
Hi, atv, no matter if it is 4K or not, can not produce an original 3D image. It can playback 3d files, but only as a 2d picture. You could playback sbs or hou files, if your tv or Beamer can put this together as a 3D file.
I am using an old mede8er for watching 3D. But this does not happen very often anymore.
