How ZynoDisplay Works

WebWorkstation

ZynoDisplay has a small set of concepts that fit together. Understanding them makes everything else straightforward.

The Building Blocks

Concept	What it is
Device	A piece of hardware running the ZynoDisplay player — a TV, tablet, streaming player, or the ZynoDisplay touchscreen.
Screen (output)	A display attached to a device. Most devices have one screen; some can drive several. Content is assigned per screen.
Media	An image, video, or video clip in your Media Library.
Playlist	A reusable, ordered sequence of media that loops. See Playlists.
Content	What a screen shows: blank, a single media item, a playlist, a web page, or a ZynoForm. See Content Types.
Display Group	A collection of screens that share default content and schedules. See Display Groups.
Schedule	A rule that plays specific content on specific days and times. See Scheduling & Dayparting.
Override	Content you push to a screen right now, temporarily, on top of everything else. See Live Overrides.

Devices Have Screens

When a device pairs, it reports its screens to ZynoDisplay. A simple tablet reports one screen; a player wired to two displays reports two. You configure each screen independently — its own content, or content inherited from a group. See Screens & Outputs.

How A Screen Decides What To Show

A screen can have several sources of content at once. ZynoDisplay resolves them in a fixed order — the first match wins:

1. Live override — anything you've pushed right now (until it expires or you clear it).
2. Schedule — the highest‑priority schedule rule whose day and time match now. A screen's own schedules take priority over its group's.
3. Screen default — the content set directly on the screen.
4. Group default — if the screen is in a group and has no default of its own, the group's default content.
5. Blank — if nothing above applies, the screen shows nothing.

TIP

Set a sensible default for everyday content, layer schedules on top for dayparting (e.g. breakfast vs. dinner menus), and keep overrides for one‑off moments like a closure notice or a flash promo.

A Typical Setup

1. Register each screen with its on‑screen code and give it a name and location.
2. Upload media and arrange it into playlists.
3. Assign content to each screen — or add screens to a group and set the content once.
4. Add schedules where content should change through the day.
5. Use live overrides and bulk actions for day‑to‑day control.
