As reported by jasper1977 in his post here, Craig Michaels from Apple has confirmed that there is no 24Hz output capability in the ATV4K. Because of this, 24Hz content (typical movie rate) is output at 60Hz instead (typical TV rate), which causes a framerate mismatch leading to visual judder. If you would like to see this change, please leave feedback at the following link. It will take less than 1 minute. Apple claims to read every single one: https://www.apple.com/feedback/appletv.html Before you take the time to respond to me about how nothing will come of this... well you might be right. But the time you took to knock me down is time that you could've posted feedback to Apple instead.
