3. Operating Instructions
The UGREEN HDMI Cable 4K facilitates high-quality audio and video transmission. Here's how to utilize its features:
- 4K@60Hz Video: Once connected, your display should automatically detect and utilize the 4K@60Hz resolution if supported by both your source and display devices. This provides a smooth and detailed visual experience.
- Audio Return Channel (ARC): If your TV and sound system support ARC, connect the cable to the designated ARC HDMI port on your TV. This allows audio from your TV's built-in tuner or smart apps to be sent back to your sound system via the HDMI cable, reducing the need for a separate audio cable.
- Ethernet Channel: The cable supports HDMI Ethernet Channel (HEC), allowing connected devices to share an internet connection without a separate Ethernet cable. Ensure both connected devices support HEC.
- HDR (High Dynamic Range): For enhanced contrast and color, ensure your source content and display device support HDR. The cable will transmit HDR signals for a more vivid picture.
- 3D Support: If your devices and content are 3D-compatible, the cable will transmit 3D video signals.
- Mirror and Extended Mode: When connecting a computer or laptop, you can configure your display settings to either mirror your primary screen or extend your desktop across multiple displays.

4. Maintenance
To ensure the longevity and optimal performance of your UGREEN HDMI Cable 4K, follow these maintenance guidelines:
- Handle with Care: Avoid excessive bending or sharp angles, especially near the connectors, to prevent internal wire damage.
- Keep Clean: Periodically wipe the cable and connectors with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners directly on the connectors.
- Store Properly: When not in use, coil the cable loosely. Avoid tight coiling or tangling, which can stress the cable.
- Protect Connectors: Keep the gold-plated connectors free from dirt and moisture. If necessary, use protective caps when the cable is unplugged for extended periods.
