How To Set Up Screen Sync For Brightsign & Samsung Tizen Devices

What Is Screen Sync?

Screen Sync is a feature that allows multiple digital signage devices to display content at the exact same time. This is especially useful for video walls, multi-screen installations, or any environment where synchronised playback creates a seamless viewing experience.

With Screen Sync, one device acts as the Master, coordinating playback instructions and ensuring all other connected devices remain perfectly aligned. This process happens automatically over the local network, providing smooth and reliable synchronisation without the need for additional external hardware.

How Users Can Benefit From Screen Sync.

Users can create synchronised content experiences by grouping screens together within the NowSignage platform. Once the desired screens are added to a Sync Group and the devices are rebooted, Screen Sync takes care of the rest. The system continuously ensures that each device stays in sync with the Master device, maintaining consistent playback across all screens.

Screen Sync is ideal for:

• Multi-screen video displays
• Retail environments requiring unified visual messaging
• Corporate or event spaces with coordinated screens

Screen Sync Local Server Requirements

To ensure successful communication between devices:

• Internal LAN communication be enabled.
  • Devices must be allowed to communicate with one another on the same local network.
• Player devices must be reachable on the network.
  • Screen sync operates by listening for synchronisation commands on port 5001.
  • The local server runs using the device's IP address and this port, allowing seamless interaction between devices.
