I know there has been talk at times about the issue cited in the title. Is there a clear understanding about what's happening these days? I don't have a device that will give troubleshooting info.

In particular I'm wondering how the Apple TV handles Youtube TV 720p@60 and 1080p@60 sports content.

I play YouTube 720p 60 & 1080p 60 often on my ATV 4K and I film in 1080p 60fps / 4K 60fps and it's all silky smooth with Match Frame Rate ON on the ATV played on a LG B7 OLED.
The whole experience is lovely!

Out of interest, I was in the Apple Store yesterday and played an iTunes trailer on the 12" iPad Pro with ProMotion and guess what? It was juddery!!!!!!!!!!!!!!! How is that possible :) When I returned home, I played the same trailer on my MacBook and guess what? It was perfect! Very bizarre :)

Well apparently the Apple TV's output is indeed 59.94 so if there's a true 60Hz source it'll depend on how elegantly your display handles it.

You can spend an entire life talking about specs and get knowhere!
it's like the people who copy each other and talk about bitrates without letting their own eyes and intelligence judge! I edit video in FCPX daily for my clients and upload to YouTube & Vimeo and don't encounter problems with the ATV.

Try it for yourself and let your eyes judge! The ATV does a great job.

I’m not sure if there is a true 60Hz source. 59.94 is based on broadcast bandwith so that’s where TVs are at.

I think there are some coming out of YouTube TV and regular YouTube.

I’m not insulting your device. You don’t have an answer to my question, it’s ok.

All 60fps video on YouTube is 59.94 that is what it is - there is no such thing as 60fps!

I do have an answer to your question which was "In particular I'm wondering how the Apple TV handles Youtube TV 720p@60 and 1080p@60 sports content."

My answer is that it handles it silky smooth. No judder on panning etc. Just perfect!

30 and 60hz = 29.97 and 59.94hz for our uses. 30 and 60hz is just a generalization we use because its easy.

To dumb down something that is surprisingly complicated, engineers needed a way to broadcast color without breaking compatibility for B&W television. Through ways I don't even care to try to understand they were able to make it work in those .06 fields.

Regardless if you look at the info/properties of a 30 or 60hz video you'll see its 29.97 or 59.94hz (errors aside).

TL;DR. Only people that know why 30 and 60hz aren't exactly that are the people that are effected by it. The rest of us can just ignore it.
