Any TV or screen with a web browser can be a hallway sign. It shows today's bells, hallway notices, upcoming events and the weather, and it takes over for every emergency alert. It never shows a roster or a student's name.

Where to find it

Choose Campus in the sidebar, then the Screens tab. Screens has three parts: Notices (short messages for the hallway), Displays (pair a TV and open the display builder) and Boards (classroom boards).

Screens → Notices: what's showing on the hallway screens now and what's scheduled.

Put a sign on a TV

  1. On Screens, open Displays.
  2. Under Hallway displays, give the screen a Board name (for example Front lobby) and choose Pair a hallway display. A short code appears. It lasts 10 minutes.
  3. On the TV, open usetrivium.com/board in its web browser and type the code.
  4. The sign starts straight away. Move the mouse (or tap) and choose Full screen.
  5. Each paired screen is listed with when it was last seen. Unpair takes one off.
Screens → Displays: paired hallway screens and Pair a hallway display.
Screens → Displays: paired hallway screens and Pair a hallway display.

The TV's pairing screen talks about Rooms → Settings. That's for classroom boards. For a hallway TV, the code comes from Screens → Displays.

Every hallway sign at your school shares one layout. Open it with Open the display builder on Screens → Displays.

The preview is your real screen. Use Time of day (Morning, During the day, After school, Evening) and the season switch beside it to see how the sign changes through the day.

Post a hallway notice

  1. On Screens (Notices), choose Post a notice.
  2. Write a short Headline, and an Extra line if you need one. You can add a photo.
  3. Set Show from and Last day.
  4. Choose Post to hallway screens. It shows as Live (or Scheduled, if it starts later) and comes down by itself after its last day. Take down removes it early.

Hallway notices are for students and visitors in the building. Announcements to families don't appear on the hallway screens, and notices don't go to families.

Classroom boards

The Boards part of Screens lists the classroom boards and sets the school's board passcode. Classroom boards are paired from each room under Rooms → Settings. See Board mode: your classroom display.

Screens and the display builder are on the web only.
