# Display Tags

**Tags** are labels you attach to displays for two purposes: keeping large fleets organized, and targeting campaigns at the right screens.

## Creating tags

Go to **Workspace → Display Tags** and click **Create tag**. Give it a name (2–255 characters). Tags are workspace-scoped — they only exist within the workspace where you create them.

You can rename or delete tags at any time. Deleting a tag removes it from all displays that had it applied.

## Applying tags to displays

Open any display's detail page and go to the **Settings** tab. Find the **Tags** field and select one or more tags. You can also type a new tag name directly in this field to create and apply it in one step.

A display can have any number of tags. Changes take effect immediately.

## Using tags for campaign targeting

When creating a campaign, choose **Schedule on display tags** as the targeting method. Then select which tags to target. The campaign will be delivered to every display that has at least one of those tags applied.

This lets you target a campaign at a logical group of screens — for example, all displays tagged `floor-1`, or all screens in a given city — without having to pick each display individually.

### Resolution-aware content

When targeting by tag, Lumicast looks at the dimensions of the matching displays and groups them by resolution (e.g. 1920×1080, 1080×1920). You can set different campaign content per resolution — so portrait and landscape screens each show an appropriately sized version.

## Tips for organising with tags

- Use tags for physical location: `building-a`, `reception`, `floor-3`
- Use tags for purpose: `break-room`, `lobby`, `warehouse`
- Use tags for region or ownership: `amsterdam`, `marketing-team`
- Combine tags — a display can have `floor-1` and `amsterdam` and `lobby` at the same time
- Keep tag names consistent across your workspace so campaigns are predictable
