6. Troubleshooting
Here are solutions to common issues you might encounter:
- Monitor Runs Hot: It is normal for the monitor to generate heat during extended use, especially when recording 4K or 6K footage. Ensure adequate ventilation around the device.

- No Input Signal: Verify that your HDMI cable is securely connected to both the camera and the monitor. Check your camera's output settings to ensure it's sending a compatible signal.
- SSD Not Recognized: If an SSD is not detected, try re-inserting it. If the issue persists, navigate to the STORAGE menu on the monitor and attempt to format the drive. Note that formatting will erase all data on the SSD.
