I recently set up a Pi to run a slideshow-style presentation for a display panel in a church lobby. I used the Pi because it allowed:
- Full automation – any schedule we need.
- Freedom from clunky, proprietary display software. The presentations use LibreOffice Impress (a free alternative to PowerPoint).
- Remote management – I don’t have to go onsite to configure settings, or to update the presentation.
- Scalability – if we decide to add more displays, they can be managed collectively.
