I bought an Nvidia Shield because the Plex client can switch the display's refresh rate to match the content (no judder for 24p content). Based on [1], it sounds like that should be possible with the Apple TV, too. Can anyone confirm if this works well?

I can't confirm with Plex specifically, but I can tell you content matching is an OS-level feature, not specific to apps. It works for the apps I've tried.

Thanks. I'm going to give the Apple TV a shot. If frame rate matching works well in other apps, it will probably be good in Plex, too.

Apple tv has plex?!! I'm getting one!

Basically every streaming device has a Plex app: https://www.plex.tv/apps-devices/
