# Screens and health

The Fleet section lists every screen your organization has claimed: what it
is assigned, when it last checked in, and whether it has caught up with what
it was last told.

## Reading a screen's status

Each screen checks in about every 20 seconds. Its status answers two
different questions:

- **Is it reachable?** When a screen misses check-ins for long enough it is
  marked offline. Screens ride out short network blips without you noticing —
  they keep playing from their local copy — so an offline mark means the
  dongle has genuinely lost power or network.
- **Is it current?** "Up to date" means the screen reports it is actually
  displaying the content you last assigned — not that the server sent it.
  A screen that is downloading a new playlist shows as catching up until the
  swap happens.

## Screenshots

From a screen's page, request a screenshot. The dongle captures what it is
rendering and sends it back — the console shows you the wall as it really
is. This is the tool for "did the new menu make it up?" and for settling
whether a screen problem is content or hardware.

## Commands

A screen answers a small set of commands from its detail page:

- **Screenshot** — capture what the panel is showing now.
- **Re-fetch content** — make the screen re-download what it should be
  showing. A repair tool for the rare case a device holds wrong bytes; it is
  not needed for ordinary publishing, which reaches screens on their own
  check-in.
- **Reboot** — restart the dongle. Admin only.

Commands are delivered on the screen's next check-in and their outcome is
reported back, so you can see whether a screen actually acted on one. A
command an offline screen never picks up expires rather than lying in wait.

## When a screen goes dark

Check power and network first — the dongle recovers from both on its own the
moment they return, and the screen catches up on everything it missed in one
check-in. If the TV is on and the network is fine but the screen stays
offline, contact support.
