Fusion Signage allows you to synchronise multiple screens so that they play content in perfect timing with each other. This can be achieved using our cloud servers or a local sync server (hosted on one of your devices).

## Pre-requisites

- Advanced or Pro Licence
- Minimum application versions:
  - Android – A-v2.5.3 (Philips BDL4550D requires A-v2.6.0)
  - Tizen – T-v2.3.7
  - WebOS – WO-v2.3.5
  - BrightSign – B-v2.3.4
  - Windows – W-v2.4.0
  - Linux – in development
- Stable internet connection and reliable local network

It’s recommended to use identical hardware for all screens to ensure optimal synchronisation results.

## How synchronisation works

You can create a group, add multiple screens to this group, and keep their content playing simultaneously. This is ideal for menu boards or multi-screen displays.

- After creating a group, screens will re-sync after each media file.
- To maximise sync accuracy, ensure each playlist has:
  - The same number of media files.
  - Equal durations for each corresponding media file.

## Handling quantity and duration

- If playlists contain different numbers of files, their contents will cycle in rotation. This will maintain the timing for synchronisation, but they will eventually play out of order.
- If media files have different durations:
  - All screens will wait until the longest media file has finished before moving on.
  - This delay won’t be noticeable with images or graphics, but videos will pause on the last frame until the longest duration is complete. Videos do not loop automatically.
