3. Setup and Connection

To ensure optimal performance and avoid potential issues, please follow these guidelines when setting up your cable:

1. Physical Connection: Ensure both ends of the cable are fully inserted into the device and monitor ports. If a device does not respond after connection, try unplugging and replugging the cable or try a different port on the device.
2. Interface Cleanliness: Ensure the device ports are clean and free of debris to prevent malfunctions due to poor connection.
3. Video Function Support: Not all device Type-C interfaces support video output. Confirm that your source device (e.g., laptop, phone) has a Type-C interface equipped with DisplayPort Alt Mode or Thunderbolt™ video output functionality before use.
4. Cable Compatibility: Ensure this cable supports the video protocol (e.g., DP Alt Mode) required by your device.

4. Operating Instructions

4.1. Fast Charging

When using high-wattage charging, ensure both the charger and the device being charged support the corresponding fast charging protocol (PD3.1 for 240W). Otherwise, maximum charging power may not be achieved.

4.2. Video Output

The cable supports single 8K/6K display output or dual 4K display output. For dual displays, two cables are required.

4.3. Data Transfer

The cable facilitates high-speed data transfer at 40Gbps, compatible with USB4 and Thunderbolt protocols.

5. Maintenance and Care

To prolong the lifespan of your cable:

• Avoid sharp bends or excessive pulling.
• Do not expose the cable to prolonged high temperatures.

6. Troubleshooting

Most connectivity issues can be resolved by checking physical connections and restarting devices.

6.1. Video Output Related Questions

Question 1: No display on monitor after connecting to a laptop/computer (C-port source device)

1. Check Physical Connection: Ensure both ends of the cable are fully inserted. Try reconnecting.
2. Check Monitor Input Source: Use the monitor's OSD menu to confirm the input source is set to the correct Type-C port.
3. Verify Device Compatibility: Confirm that the specific Type-C port on your computer supports video output (DisplayPort Alt Mode or Thunderbolt™). Refer to your device's manual or official specifications.
4. Check System Settings: In your computer's operating system (e.g., Windows 'Display Settings' or macOS 'System Preferences > Displays'), check if the external monitor is detected. Try selecting "Detect" (Windows) or "Identify" (macOS).
5. Restart Devices: Try restarting your computer and monitor. This can resolve temporary software or driver conflicts.
6. Check Cable Compatibility: Ensure this cable supports the video protocol (e.g., DP Alt Mode) required by your device.

Question 2: No signal on monitor when connected to a phone

1. Confirm Phone Support: The vast majority of phones require support for DP Alt Mode or a similar desktop mode (e.g., Samsung DeX, Huawei EMUI Desktop Mode) to output video via Type-C. Confirm your phone model supports this feature.
2. Enable Desktop Mode: Some phones require manually enabling desktop mode from the notification shade after connection.
3. Restart Devices: Try restarting the phone and the monitor.
4. Use an Adapter: Some monitors might require a specific adapter or dock for compatibility with phones. Check compatibility notes for your phone and monitor.

Question 3: Display is present but resolution/refresh rate is incorrect

Solution: Check the device's display settings, confirm if multiple displays are recognized, and manually adjust the resolution and refresh rate. Update the computer's graphics card drivers.

6.2. Charging Related Questions

Question 4: Slow charging speed

Solution: Confirm whether the charger and the device support the PD3.1 or corresponding fast charging protocol. Try using a different power adapter that supports fast charging.

6.3. Data Transfer Related Questions

Question 5: Data transfer speed lower than expected

Solution: Confirm if the device ports support USB4 or Thunderbolt™ protocols. Check if the cable is fully inserted. Rule out port contamination or damage.

Question 6: Device does not recognize the cable at all

Solution: Try connecting the cable to other devices to check if it functions normally. Clean the ports. Restart the device and try again.
