A playlist plays on a screen when four things are all true at once. Nothing else is involved.
- The playlist is enabled. A disabled playlist stays assigned but never plays.
- The screen is in its target. Either named directly, or carrying a label the playlist targets.
- The screen is enabled. A disabled screen holds no license and shows nothing.
- The schedule matches right now, in that screen’s local time.
When several qualify at once
They share the screen, cycling in alphabetical order of title, unless one is a priority playlist, which takes the screen for as long as its schedule is active. When several playlists are eligible and Priority override cover both.
Why this list is worth memorizing
Almost every “why is it showing that” question is one of those four, and they fail in a specific order of likelihood: schedule first, then the label not matching, then the playlist being disabled.
Two shortcuts settle it faster than reasoning about it. The Now playing tab on a screen lists what is active on that screen right now. The effective schedule summary on a playlist says in plain language when it will play.
Case matters in labels
Warehouse and warehouse are two different labels. This is the most common cause of a playlist that is correctly built, correctly enabled, and quietly playing on nothing.
