6. Troubleshooting
- No Picture/Sound:
- Ensure the HDMI cable is securely connected to both the source and display devices.
- Verify that the correct HDMI input is selected on your display device.
- Check if both devices are powered on.
- Test with another HDMI cable if available to rule out device issues.
- Picture Flickering/Intermittent Signal:
- Ensure the cable is not bent sharply or damaged.
- The Vention cable's multi-layer shielding (Aluminum foil + GND + Metal braided mesh) is designed to prevent "splash" and "ghosting." If issues persist, try a different port or device.
- Reduce the resolution or refresh rate in your device settings to see if the issue is related to bandwidth limitations of older devices.
- No 8K/4K@120Hz/HDR:
- Confirm that both your source device and display device support HDMI 2.1 and the desired resolution/refresh rate.
- Ensure that HDR, VRR, and other advanced features are enabled in the settings of your source and display devices.
- Audio Issues (e.g., no Dolby Atmos):
- Verify that your audio system and display device support eARC and the specific audio formats (e.g., Dolby Atmos).
- Check audio settings on both your source and display devices.
7. User Tips
- For optimal performance, especially with 8K@60Hz or 4K@120Hz, ensure all connected devices (source and display) are HDMI 2.1 compliant.
- When connecting to a gaming console like PS5 or Nintendo Switch, enable VRR and ALLM settings on your TV/monitor for the smoothest gaming experience.
- Utilize the various display modes (mirror, extend, multi-split) to enhance your productivity or entertainment setup.
- Always handle the cable by the connectors, not the cable itself, to prolong its lifespan.
