Setup
- Identify Compatible Ports: Ensure your device (laptop, monitor, docking station, etc.) has a USB-C port that supports USB4 or Thunderbolt 3/4.
- Connect the Cable: Insert one end of the Silkland USB 4 Cable into the USB-C port of your host device (e.g., laptop).

- Plug and Play: The cable is designed for plug-and-play functionality. No additional drivers are typically required for basic operation.
Operating Instructions
- Data Transfer: Connect the cable between two compatible devices to initiate high-speed data transfer. The actual speed may vary depending on the capabilities of both connected devices.
- Charging: Connect the cable between a compatible power source (e.g., 240W GaN charger) and your device (e.g., laptop, smartphone) for fast charging. The E-Marker chip ensures safe and efficient power delivery.
- Video Output: Connect your laptop or docking station to a compatible monitor using the cable for video display. Ensure your device supports DisplayPort Alt Mode for optimal resolution and refresh rates (e.g., 8K@60Hz or dual 4K@60Hz).

Troubleshooting
- No Display Output:
- Ensure your source device (laptop) and display support DisplayPort Alt Mode over USB-C.
- Verify that the monitor input is set to the correct USB-C/Thunderbolt port.
- Test with another compatible cable or device to isolate the issue.
- Slow Data Transfer Speed:
- Confirm that both the host device and the peripheral device support 40Gbps (USB4/Thunderbolt 3/4).
- Ensure all connected devices are functioning correctly and are not bottlenecking the speed.
- Device Not Charging:
- Verify that your power adapter and device support USB Power Delivery (PD) and the required wattage (up to 240W).
- Check if the cable is securely connected at both ends.
- Intermittent Connection:
- Ensure connectors are clean and free of debris.
- Avoid placing heavy objects on the cable or bending it sharply.
