The old way: overnight syncs and reboot carts
A lot of legacy signage software still works like this: you upload a change during the day, and the screen itself only picks it up on its next scheduled sync - sometimes hourly, often overnight. If something needs to go live right now, the fallback is walking over to the screen and rebooting it, or plugging in a USB stick. That's fine for a menu board that changes twice a year. It falls apart the moment you need to react to something today.
How DisplayNyx pushes instantly
The DisplayNyx player app - whether it's running on a Windows PC, a Mac, a Linux mini-PC, or an Android box - keeps a live connection back to your dashboard. There's no polling schedule to wait out. The moment you publish a change, it's sent straight to every connected screen it applies to, and shows up there in seconds.
- Swap a promo image or video, and it's live everywhere it's assigned - no reboot, no re-sync.
- Update a price on a menu board the second it changes, not at the next scheduled refresh.
- Push a live announcement - a closing-time reminder, a recall notice, a weather delay - and it takes over the screen immediately.
Why this matters for multi-location teams
The value compounds with every extra screen and store you add. A single-screen café can live with an overnight sync. A ten-store franchise chain that needs the same weekend promo live everywhere at 9am on Saturday - or a pharmacy that needs a recall notice up the instant it's issued - can't. Instant push is what makes "push it once, live everywhere" actually true, instead of "push it once, live everywhere by tomorrow."
