Massive judder on AppleTV depending on Hz

[0987623]

Hello i recently unfortunately
noticed a problem which I cannot solve per se: I have an Apple TV 4K and have activated the "adapt to frame rate" option.
Netflix, Amazon, iTunes Movies etc. They all run perfectly, the display becomes short
black and then it is displayed in the original frame rate. But:
YouTube doesn't seem to support this: when I turn my Apple TV to 4k 60
Hz point, all 60hz videos and content from YouTube and also the original run
Apple screensaver smooth.
However, if I set it to 50 Hz, the screen saver will no longer run
smooth and jerky, YouTube then runs 50 Hz videos smoothly,
The 60 Hz videos don't.
Generally everything runs smoothly at 50 Hz, except for the menu, the
Screensaver and stop YouTube. Quite a bit jerky at 60 Hz,
despite the "adjust to frame rate" option. For example, the SkyQ app: it always plays content smoothly as long as I set it to 50HZ. As soon as I set to 60Hz, massive stutters. Regardless of whether the film is 24HZ or 30hz, at 50Hz setting everything works well, at least within the skyq app. unlike YouTube described earlier.

My TV is the Samsung MU6179 55´. There "Motion plus" was also switched on and off by me to test whether it makes a difference. That was not the case. Deactivating "digitally processing" also did nothing. No matter what HDMI cable. All the same problem.

frame rate matching has to be enabled by the developers of each app, Apple gives them the framework, but the app has to tell the OS that it needs to happen.

apple's menus should be at whatever "default" you've chosen. if it seems jerky, I would think it's the TV instead of the aTV making that happen.

I don't think screen savers will make matching enable, They seem to just match whatever setting (resolution and range) is being output at the moment, see here
it's possible that it doesn't look at rate when choosing, so all of your 4k screensavers have been downloaded in 60, so that's just what it played.

The aTV YouTube app doesn't really have the best video player, and it doesn't support 4k
and just because a video is listed at a certain frame rate. I never trust it to actually play at that rate.

on my old Panasonic TV, it had an info button, you could hit that and the video specs would show up on screen, including frame rate.
My new LG, doesn't do that, It just has resolution and range.
your TV might have something similar, so you can see actual numbers, to get a better handle on what's going on.
