Troubleshooting & Repair
This guide is for deployments where Ouva runs in Chrome kiosk mode on always-on displays, including single-screen and video-wall installations.
Quick Triage Checklist
Section titled “Quick Triage Checklist”Before deep troubleshooting, capture the following:
- Site name, room, and affected display(s)
- Whether the issue affects one panel or the full wall
- Current local time and when the issue started
- Photo of the screen state and any visible error message
No Image on Any Screen
Section titled “No Image on Any Screen”- Confirm every display is powered on and set to the correct input.
- Confirm the kiosk PC is powered on and not asleep.
- Reseat display-path connections (HDMI/DVI/fiber/extender hardware) and verify power LEDs on intermediate devices.
- Connect a known-good monitor directly to the kiosk PC output.
- If no image appears, troubleshoot the kiosk PC or GPU.
- If image appears, the issue is in the cable/extender/video-wall path.
One Panel Is Blank or Out of Sync in a Video Wall
Section titled “One Panel Is Blank or Out of Sync in a Video Wall”- Verify power and input source on the affected panel.
- Swap the panel’s cable or input path with a known-working panel when possible.
- Confirm video-wall controller mapping and tile assignment.
- If your deployment uses sender/receiver extenders, test with a known-working pair to isolate cable vs extender faults.
Ouva Not Visible in Chrome Kiosk Mode
Section titled “Ouva Not Visible in Chrome Kiosk Mode”- Confirm Chrome launches in kiosk mode and opens
https://app.ouva.co. - Restart Chrome, then restart the kiosk session or device.
- Verify network connectivity and that system date/time are correct.
- If sign-in fails repeatedly, confirm account access and network allowlists from Network Guidelines.
Scheduled Uptime Is Not Being Followed
Section titled “Scheduled Uptime Is Not Being Followed”- Confirm the kiosk device timezone and clock are correct.
- Verify scheduled uptime configuration and active days/hours.
- Disable conflicting OS power plans (sleep, hibernate, auto-display-off).
- Restart scheduling components or reboot the kiosk device after schedule changes.
Performance Issues (Stutter, Low FPS, Input Lag)
Section titled “Performance Issues (Stutter, Low FPS, Input Lag)”- Ensure hardware acceleration is enabled in Chrome.
- Close background apps and extra browser tabs.
- Lower output resolution if the wall or display is running above required resolution.
- Update GPU drivers and restart the browser/device.
When to Escalate to Ouva Support
Section titled “When to Escalate to Ouva Support”Escalate when the same issue persists after the checks above, or when repeated outages occur.
Include:
- Site and room name
- Device identifier (if available)
- Time of incident and recurrence pattern
- Photos or video of the affected display(s)
- Results of direct-output and cable/extender isolation tests
