How to Run a Wallboard Display With Chrome

By the Pick Ads team · Tested on Chrome · Published October 20, 2026 · Updated October 20, 2026

Short answer: Connect a small computer to the TV and create a dedicated Chrome profile with --user-data-dir. Launch it full screen with --kiosk, sign in to each dashboard once, and add a tab rotator to cycle and refresh the pages. Then fix sleep, sign-in timeouts and restart recovery at the operating system and app level. Test a reboot before you leave it.

A wallboard is a shared screen that shows live team numbers: queues, sales, uptime, builds. In the US you'll usually hear it called a dashboard on a TV. The setup is the same either way.

Kiosk setup

Chrome's --kiosk launch switch turns on Chrome's kiosk mode. Chrome's own source notes that this "is not Chrome OS kiosk mode", which is managed separately on ChromeOS devices. Two other switches help on a wallboard: --user-data-dir keeps the wallboard's cookies and settings in their own folder, and --no-first-run skips first-run screens.

Example launch commands:

  • Windows: "C:\Program Files\Google\Chrome\Application\chrome.exe" --kiosk --no-first-run --user-data-dir="C:\Wallboard\ChromeProfile" https://your-first-dashboard.example
  • macOS: open -na "Google Chrome" --args --kiosk --no-first-run --user-data-dir="$HOME/WallboardProfile" https://your-first-dashboard.example
  • Linux: google-chrome --kiosk --no-first-run --user-data-dir="$HOME/wallboard-profile" https://your-first-dashboard.example

Don't add --incognito. Our login guide lists incognito windows and cleared cookies after a reboot as common causes of login screens on TVs. To leave kiosk mode for maintenance, close Chrome with the keyboard.

Kiosk mode is one layer of a stack: OS, Chrome, extension and dashboard permissions. Chrome kiosk mode for dashboard TVs explains which part controls what. Tab Rotator doesn't switch Chrome into kiosk mode for you.

Rotation and refresh settings

  1. Open each dashboard once in the wallboard profile and sign in.
  2. Install a rotator. In Tab Rotator, select the tabs or save them as a playlist of URLs. A playlist lets the wallboard rebuild itself after a restart.
  3. Set the time per page. Tab Rotator Free allows 5 seconds to 60 minutes per rotation and up to 5 tabs. Per-tab timing is Premium.
  4. Choose refresh. Tab Rotator refreshes each page after it's shown, with normal or hard refresh. Pick an interval longer than the slowest page takes to load. How often should a dashboard refresh? has starting points by dashboard type.
  5. Turn on "start when Chrome opens" and keep-awake. Turn on pause-while-in-use if people sometimes use the machine.

Staying logged in

Most wallboard failures are login screens, not rotation problems. Common causes are idle timeouts, maximum session lengths, password changes and cleared cookies. A refresh can reload a valid session, but it can't complete multi-factor sign-in. Ask IT for a display account or longer session that fits your security policy. Where the app offers it, a read-only public or share link avoids sign-in entirely. See why your TV dashboard keeps showing a login screen.

Recovery after restart

Plan recovery in order:

  1. The computer powers on and signs in by itself (if policy allows).
  2. Chrome starts with your kiosk command.
  3. Tabs come back, ideally from a playlist.
  4. Rotation resumes without a click. Tab Rotator lists resuming after a crash, power cut or update.

Test each layer during a maintenance window. Recover a dashboard after a restart has a checklist of what to record. For sleep, change the OS and TV power settings first. Treat keep-awake as a helper (prevent display sleep).

Examples

  • Support wallboard: queue and SLA views from your help desk. Zendesk now signs team members out after at most 12 hours, so an agent login won't run all week. See showing a Zendesk dashboard on a TV.
  • Sales: a leaderboard sheet and the CRM pipeline view. Premium can show a live data table from Google Sheets or CSV.
  • Operations: uptime and status pages, which are light and can refresh often.
  • Engineering: build status and error-rate dashboards. Heavier pages need longer refresh intervals.

FAQ

What hardware is enough?

How do I stop sleep? Set the computer's sleep and display-off settings to never during working hours, and turn off the TV's own auto-off timer. Then use a keep-awake option such as Tab Rotator's as a helper. Chrome's power API lets extensions keep the display from dimming or turning off.

How often should dashboards refresh? There's no universal number. Match the refresh to how often the data changes and how long the page takes to load on your hardware. Slow-moving KPIs may need a refresh every few minutes. Ops boards can refresh faster, but never faster than the page can render.
