I'm developing something so that everyone can do this easily[0]. It's a plugin based presentation software. Real time connection through websocket.
So all you need to do is create a project and use a plugin(existing or your own) to generate your view. The plugin is flexible, so it could be a custom UI or uploading a HTML file for example.
Then, you can open a link on any machine like the e-ink display.
Open-source and self-hostable. But you can also use the online version I'm hosting.
It's still very new so things will break but I'm already using it in church and other meetings.
