01Screen URLs
Open the TV's web browser, go to the URL for that panel, and set it as the homepage / bookmark. Generated live from the current configuration.
A video wall shows one item across several panels, so it gets one URL per panel — open each panel at its own tile URL. Tile 0 is the top-left panel, counting left to right, then top to bottom.
02One-time TV settings
These live in the TV's own menus — a web page can't override them. Do this once per screen.
- Turn off the screensaver / screen saver. Settings → General → System / Power & Energy Saving.
- Disable Eco / energy-saving auto-dimming and ambient light detection so brightness stays constant.
- Disable auto power-off / sleep timer / "no-signal" power off.
- Set the browser homepage to this screen's URL so it reopens to the right place.
- Turn sound to mute or a fixed level — the player autoplays video muted by design.
- Set the TV clock to sync automatically (NTP). Wall panels stay in sync using the device clock.
03Adding & changing content
Change content in the content manager — or edit playlists.json and commit — and it goes live within a couple of minutes. The players poll for updates and reload themselves, so there is no need to touch any TV.
Some external sites refuse to load inside a frame (X-Frame-Options / CSP). Content you own can be whitelisted; for third-party pages, use a published-to-web link, an exported image/video, or a screenshot. Test each new piece before relying on it.
Add ?debug=1 to any screen URL to show a diagnostic badge on that TV.
