Care and Maintenance
To ensure the longevity and optimal performance of your Hagibis HDMI 2.1 cable, follow these care and maintenance guidelines:
- Handle with Care: Avoid excessive bending, twisting, or pulling of the cable, especially near the connectors.
- Clean Connectors: If connectors appear dusty, gently wipe them with a dry, lint-free cloth. Avoid using liquid cleaners directly on the connectors.
- Storage: When not in use, store the cable in a clean, dry place, preferably coiled loosely to prevent kinks.
- Environmental Conditions: Avoid exposing the cable to extreme temperatures, direct sunlight, or high humidity.
- Secure Connections: Ensure connectors are fully inserted into ports to prevent signal loss or damage. Do not force connections.

Troubleshooting
If you encounter issues with your Hagibis HDMI 2.1 cable, try the following troubleshooting steps:
- No Picture/Sound:
- Ensure both ends of the HDMI cable are securely connected to their respective ports.
- Verify that your display device is set to the correct HDMI input source.
- Check if both your source and display devices are powered on.
- Try connecting the cable to different HDMI ports on your display device, if available.
- Test with another HDMI cable to rule out issues with the source or display device.
- Poor Picture Quality (Flickering, Artifacts):
- Ensure your source device's output resolution and refresh rate are compatible with your display device.
- Check for any kinks or damage to the cable.
- If using an HDMI switch or adapter, try connecting the cable directly to the display.
- HDCP Issues (Protected Content Not Displaying):
- Some devices, particularly gaming consoles, may have specific requirements for HDCP (High-bandwidth Digital Content Protection) signal transfer. Ensure all devices in the chain (source, cable, display, and any intermediate switches) are HDCP 2.2 or 2.3 compliant for 4K/8K content.
- If using an HDMI switch, ensure it is also HDCP compliant and try bypassing it if issues persist.
- Features Not Working (e.g., 8K, 4K@120Hz, VRR):
- Confirm that both your source device and display device fully support the specific HDMI 2.1 feature you are trying to use. Many features require explicit activation in device settings.
- Update firmware on your source and display devices to the latest versions.
