A CLOCK ON EVERY SCREEN
On any display you already own.
Any browser on the same network can open the live studio clock, perfectly synced to the master. No app to install on the viewing device, no extra licence, no per-screen cost - if it has a web browser, it can be a StudioClock display.

Any TV with a browser
Most smart TVs (Samsung Tizen, LG webOS, Android TV and similar built-in browser apps) can open a plain URL directly - no signage software required for a simple case. Point the TV's browser at the address and it becomes a live studio clock. For a more managed, always-on deployment, or for hardware without a friendly built-in browser, use a dedicated signage player or a small always-on computer instead.
Signage players that accept a URL
Each of these has a webpage or URL content type built in, which is all the LAN viewer needs.
An HTML5/webpage state in a presentation, via BrightAuthor:connected or direct HTML publishing.
Use Links in Studio: paste the URL, it verifies the page loads, then schedule it to a screen.
Add Web Page, paste the URL, set a duration or Forever, and optionally a fallback image.
A Webpage Widget in a Region, rendered unmodified or scaled to fit.
A Webpage asset under Assets, with zoom level and a load-time fallback.
Samsung's URL Launcher installs a web app on the display itself; LG's SuperSign Cloud deploys URLs to webOS 4.0+.
A Raspberry Pi kiosk behind a monitor
The cheapest, most flexible dedicated wall clock: a Pi running a browser in kiosk mode, hidden behind the monitor it drives. A Raspberry Pi Zero 2 W is enough for a single always-on tab. If the monitor is hidden and its remote is out of reach, cec-client can power the screen on and off over the HDMI cable itself.
Raspberry Pi OS plus Chromium, launched from a systemd service so it comes up full-screen on every boot with no desktop visible.
A ready-made Pi image for exactly this: flash it, set the URL and Wi-Fi in the boot configuration, and it boots straight to the page full-screen.
An open-source signage platform for the Pi with a web scheduler, if you want scheduling rather than a single always-on page.
Wake and sleep the panel with the Pi rather than reaching behind it.
Old iPads and Android tablets
On iPad, Guided Access locks the device to Safari showing the StudioClock URL, disabling swipes and other apps - set Auto-Lock to Never first so the screen does not sleep (guide). On Android, a dedicated kiosk browser such as Fully Kiosk Browser locks the tablet to a single URL full-screen, hiding system navigation.
Precision and security
Every LAN viewer disciplines itself to the same master clock as the studio output: it takes lowest-round-trip-time offset samples from StudioClock's own time sync (an NTP-style exchange over the viewer's WebSocket connection), then ticks smoothly and locally between samples - so a browser three rooms away shows the same accurate time as the studio output, without a flood of network traffic. The viewer is read-only by design: it can never control the show. For anything beyond a trusted studio LAN, secure network mode adds an optional viewer passcode and can restrict the server to localhost only.
