Apple 4K tag

I use the Plex client on a Samsung TV and I would like to request an option to tag movies as available in Apple TV on 4K. I have a local HD version and also a 4K copy available in iTunes, which I would prefer to play. This new tag would be great to remind f the versions I have available.

Not quite sure I understand your request.
You want to have some kind of indicator that you have another version of that video on a 3rd party platform (specifically in your iTunes / Apple TV environment)?

There’s been some requests in the past to allow for some level of integration, e.g.

Yes, your description of my feature is correct. To make it helpful for a user, if a tag / indicator was introduced I would know I have a higher quality TV / Movie available elsewhere, rather than having to check if I have purchased a 4K option in iTunes.

I understand the issues surrounding linking from Plex to other online streamers, so thought this would be an easier option.

2023 clean-up: there’s a similar suggestion focusing on linking content available to you in a different ecosystem into your libraries using the Discover features.
