# Themes and Customization for Room Displays

Meeting Room 365 includes branding and layout customization at no extra charge. Most changes apply instantly from the admin portal; some (like display scale) require a tablet restart.

Configure appearance under the **Style** tab and **Description** tab when editing a display at [admin.meetingroom365.com](https://admin.meetingroom365.com).

## Theme generations

Meeting Room 365 offers three theme generations. Pick one per display in the **Theme Editor**.

| Generation | Status | Summary |
|------------|--------|---------|
| **v2 Theme** | Default legacy | Basic themes, broad CSS customization, best compatibility with older devices |
| **v3 Theme** | Recommended | Simpler setup, timeline/time-grid/calendar views, collapsible upcoming meetings |
| **SDK Theme** | Preview | Modern designer-built themes with per-theme options (Signal, Cumulus, Meridian, Reykjavik, Magnolia, Atrium) |

The Theme Editor includes a live preview iframe. SDK themes are labeled as a **preview release** in the admin portal — options may expand over time.

To **replace the entire UI** with your own hosted app (not just pick a preset theme), use a **Custom** display and the [Custom displays & SDK](../sdk/index.md) guide.

## SDK themes

Six SDK themes are available when **SDK Theme** is selected:

| Theme | Notable options |
|-------|-----------------|
| **Signal** | Accent (lime, cyan, amber, magenta, mint, violet); density (minimal, full) |
| **Cumulus** | Accent (cumulus, sage, iris, dark); density (minimal, regular, informative); subtitle; hide "I'm" prefix |
| **Meridian** | Accent (amber, cobalt, sunset, terminal); density (compact, regular, comfy); room zone label; help text; hide schedule |
| **Reykjavik** | Accent hue (0–360°); density (compact, spacious) |
| **Magnolia** | Density (compact, regular, informative); amenities line |
| **Atrium** | Timeline mode (rail, right strip, side pane, bottom, overlay); status-bound background; background image or video |

Only **Atrium** supports a custom background image or video among SDK themes. Built-in animated background presets (sphere, aurora, earth orbit, and others) are available in the theme editor.

## Legacy themes (v2 and v3)

### v2 theme styles

Choose one layout when **v2 Theme** is active:

- **Minimalist** — latest v2 layout with common options
- **Split** — simplified; does not show upcoming meetings
- **Status-bound** — background color shifts with occupied/available state
- **Glass** — glassmorphism styling
- **Default** — full-featured classic v2
- **Existing** — preserves your current custom CSS without overwriting

v2 supports the richest **custom CSS** workflow.

### v3 theme options

When **v3 Theme** is active, additional toggles include:

- **Show Timeline** — schedule rail on the right
- **Enable Time Grid** — time-grid view instead of timeline
- **Enable Calendar View** — month calendar view
- **Show Status-bound Background** — background syncs to room state
- **Show Status Bars** — colored bars indicating availability

Custom CSS for v3 is stored separately from v2 (`v3Styles` vs classic styles in the admin editor).

## Branding options

Available on the **Style** and **Description** tabs:

| Option | Description |
|--------|-------------|
| **Logo** | Upload or paste a logo URL; optional logo width |
| **Background image** | JPEG or PNG; optional fullscreen cover mode |
| **Animated background** | Video or HTML background URL |
| **Room photo** | Photo shown on schedule-related views |
| **Email logo** | Horizontal white logo for notification emails |
| **Message banner** | Short text displayed atop the screen (Description tab) |
| **Room metadata** | Name, location, description, capacity |
| **Equipment icons** | Icon set describing room amenities (e.g. video, Wi‑Fi, TV) |
| **Brand color** | Used on status-board-style elements where applicable |

## Custom CSS

The **CSS & Custom Styles** editor accepts overrides for v2 or v3 displays. Use browser developer tools against a preview display to test selectors, then paste CSS into the editor and save.

Marketing materials also reference **custom scripts and modal windows** for advanced integrations — contact [support](mailto:support@meetingroom365.com) for embedded modal flows, custom CSS beyond the editor, or other theme tweaks. These are typically configured the same business day.

## Localization

Displays ship with **16 languages** out of the box. Configure under the **Localization** tab:

| Setting | Effect |
|---------|--------|
| **Language preset** | English, Spanish, German, French, Dutch, Italian, Polish, Danish, Portuguese, Russian, Estonian, Arabic, Greek, Japanese, Korean, Traditional Chinese, Simplified Chinese, or Custom |
| **Display locale code** | Overrides preset (e.g. `en-US`, `ja-JP`) |
| **24-hour time format** | 24:00 vs 12-hour am/pm |
| **International date format** | Day-before-month ordering |
| **Asian date formatting** | Locale-specific date strings |
| **Custom i18n JSON** | Edit individual UI strings; save to apply |

Right-to-left languages are supported. Some translation presets were built for v2 first — you may need to add strings for newer v3 or SDK controls.

## Display scale

**Scale / Force Display Width** (800–1280, default 1024) adjusts element sizing for different screen sizes. Changing scale requires restarting the tablet app.

## Supported / not supported

| Supported | Not supported |
|-----------|---------------|
| v2, v3, and SDK theme generations | Theme editor inside native kiosk app UI (configure via admin portal) |
| Six SDK themes with per-theme options | Unlimited arbitrary HTML injection without review (use custom CSS/scripts thoughtfully) |
| Custom CSS on v2 and v3 | |
| 16 built-in languages + custom JSON overrides | |
| Logo, background, video, room photo, email logo | |
| Message banner and equipment icons | |
| MDM-provisioned displays still receive theme updates from the cloud | |

## Best fit for

- **Brand-conscious enterprises** that want lobby-grade visuals on every floor without a separate signage vendor
- **Global offices** localizing date formats and UI copy for regional offices
- **Design-led workplaces** piloting SDK themes (Signal, Atrium, Meridian) for a modern aesthetic
- **Legacy tablet fleets** staying on v2 for maximum CSS control and older OS support

## Frequently asked questions

**Which theme works on old iPads?**  
iOS 15+ and Android 5.1+ are recommended for new deployments. Very old operating systems may run **v2** display themes only — see [Hardware and devices](./hardware-and-devices.md#recommended-os-versions).

**Do SDK themes cost extra?**  
No. Customization is included in the standard display subscription.

**Can I copy styling to many displays?**  
Yes. Use **Clone Display Properties**, location groups, or mass-update tools in the admin portal to apply the same theme to a floor or building.
