HDMI™ issues can prevent a ClickShare Hub device from displaying content correctly, impacting meetings and usability. This guide outlines key steps to diagnose and resolve HDMI™ related problems.
Step 1: Check Physical Connections
-
Secure HDMI™ Cable: Ensure the HDMI™ cable is firmly connected to both the ClickShare Hub device and the display.
-
Try a Different Port: Switch to another HDMI™ port on the display to rule out port failure.
-
Inspect the Cable: Look for visible damage or try a known working HDMI™ cable.
Step 2: Verify Display Settings
-
Correct Input Source: Make sure the display is set to the correct HDMI™ input.
-
Resolution Compatibility: Confirm the display supports the resolution output by the ClickShare Hub (see Supported HDMI™ Resolutions on ClickShare Hub Devices).
-
HDCP Support: Some displays may have issues with HDCP (High-bandwidth Digital Content Protection). Try disabling HDCP if supported by the device.
-
CEC Support: Check if HDMI™-CEC (Consumer Electronics Control) is enabled on both the ClickShare Hub and the display. CEC allows devices to control each other over HDMI™ (e.g., power on/off, input switching). If you experience unexpected behavior such as the display not waking up or switching inputs, try toggling CEC settings or disabling it to isolate the issue.
Step 3: Restart Devices
-
Power Cycle: Turn off both the ClickShare Hub device and the display, wait 10 seconds, then power them back on.
-
Boot Sequence: Ensure the display is powered on before the ClickShare Hub device to allow proper HDMI™ handshake.
Step 4: Check Device Settings
- Access Admin Settings:
-
Tap the gear icon on the Teams interface and enter the admin password.
-
-
Display Configuration:
-
Navigate to Device Settings > Display
-
Adjust resolution or refresh rate if available.
-
Step 5: Test with Alternate Equipment
-
Try Another Display: Connect the ClickShare Hub device to a different monitor or TV.
-
Try Another Source: Connect a laptop or other HDMI™ source to the original display to confirm it works.
Step 6: Perform a Reset of the ClickShare Hub
- Changing your display configuration may result in incompatible display configurations in the MTR configuration.
-
Resetting the ClickShare Hub clears previous configurations.
-
Navigate to Device Settings > Admin > Troubleshooting
-
Initiated a Factory Reset
-
Step 7: Contact Support
If the issue persists:
-
Barco Support: Use the Barco support portal to open a support ticket for hardware-specific troubleshooting.
-
Microsoft Support: Use the Microsoft 365 admin portal to open a support ticket if the issue appears software related.
Final Tips
-
Document the issue with photos and/or logs if escalating to support.
-
Keep spare HDMI™ cables and adapters on hand for quick swaps.
