Yeah, I watched The Road To El Dorado yesterday on a giant cinema screen. The surroundings actually gently change color depending on what’s showing on your flat screen. I just wish you could choose a black void as surroundings. But the default starry sky is dark enough.

I used the normal Jellyfin Desktop app installed as a flatpak through Discover.

You don’t even have to use the desktop mode. All newly installed apps are added to a menu on your dashboard, plus some of the already installed ones are there. No idea how they chose what to put on there and I fear it will become cluttered with time. But for now it is nice. Given time we’ll probably be able to change it.
