Maintenance
To ensure the longevity and optimal performance of your VENTION HDMI 2.1 cable, follow these maintenance guidelines:
- Handle with Care: Avoid excessive bending, twisting, or pulling of the cable, especially near the connectors. The nylon braided jacket provides durability, but extreme stress can still cause 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 kinking, which can damage the internal wires.
- Protect Connectors: Keep the gold-plated connectors free from dirt and moisture. If necessary, use a small brush to gently clean any debris from the connector pins.
