I’m trying to set up a dashboard to display on a TV screen for continuous monitoring, and I’m looking for the best way to handle auto-refresh and session timeout.
Current setup
A ServiceNow dashboard (PA dashboard)
Displayed on a TV (either directly via TV browser or through a connected device)
Requirement is to auto-refresh the dashboard at regular intervals (e.g., every 1–5 minutes)
What I’ve tried
Using URL parameter:
&sysparm_refresh_interval=60
This works in some cases, but not consistently across all environments/devices
Challenges
Auto-refresh reliability
TV browsers or certain setups don’t always honor the refresh parameter
Need a stable way to ensure continuous refresh without manual intervention
Session timeout
After a period of inactivity, the session expires and the dashboard stops updating
Looking for ways to handle or mitigate session timeout for always-on displays
What I’m looking for
Recommended approach for reliable auto-refresh on dashboards used for wallboards/TVs
Best practices for handling session timeout in long-running display scenarios
Whether others are using:
Browser extensions / scripts
Kiosk mode setups
Dedicated devices instead of TV browsers
Any guidance or patterns that have worked well in similar setups would be really helpful.
Thanks in advance!
