Hi, I have code an magic TV with MagicMirror app (v2. 13, never update it!) for my company.
It display some information (read directly from database,) and slide show photos, internal document.
It’s just an rpi3B+ used in local (for technician hall) with an 27’ screen computer and remotely (server mode for hall of the company) with a 100’ smart tv
Works fine since ~2y now
