Setup

1. Unpacking: Carefully remove the Thunderbolt 5 cable from its packaging.
2. Inspect Cable: Before first use, visually inspect the cable for any signs of damage, such as kinks, cuts, or bent connectors.
3. Identify Ports: Locate the compatible Type-C ports on your source device (e.g., laptop, phone) and target device (e.g., monitor, external SSD, charger).
4. Connect Devices: Insert one end of the Thunderbolt 5 cable firmly into the Type-C port of your source device and the other end into the Type-C port of your target device. Ensure a snug fit.
5. Verify Compatibility for Video Output: If using for video output, confirm that your source device's Type-C interface supports DisplayPort Alt Mode or Thunderbolt™ video output functionality. Not all Type-C ports support video output.

Operating Instructions

1. For Charging

• Connect the cable between your device and a compatible PD3.1 (or lower) fast charger. The cable supports up to 240W (48V/5A) power delivery.
• Ensure both your charger and the device being charged support the corresponding fast charging protocol to achieve maximum charging power.

2. For Data Transfer

• Connect the cable between two compatible devices (e.g., computer and external SSD) to transfer data at speeds up to 120Gbps (unidirectional) or 80Gbps (bidirectional).
• Ensure both connected devices support USB4 or Thunderbolt™ protocols for optimal data transfer speeds.

3. For Video Output

• Connect the cable from your source device (e.g., laptop) to a compatible monitor or display.
• The cable supports resolutions up to 16K@30Hz, 8K@60Hz (dual displays), or 4K@120Hz (triple displays) via DP2.1 protocol.
• If connecting to a phone, some phones may require enabling a 'Desktop Mode' (e.g., Samsung DeX, Huawei EMUI Desktop Mode) from the notification panel.

Usage Precautions

1. Video Function Support: Not all device Type-C interfaces support video output. Confirm your source device (e.g., laptop, phone) has a Type-C interface equipped with DisplayPort Alt Mode or Thunderbolt™ video output functionality before use.
2. Interface Cleanliness: Ensure device ports are clean and free of debris to prevent malfunctions due to poor connection.
3. System Status: During high-speed data transfer or video output, connected devices should be in normal operating mode to avoid interruptions caused by system sleep or insufficient performance.
4. Fast Charging Protocol: When using high-wattage charging, ensure both the charger and the device being charged support the corresponding fast charging protocol; otherwise, maximum charging power may not be achieved.

Maintenance and Care

• Cable Care: Avoid sharp bends, excessive pulling, or prolonged exposure to high temperatures to prevent affecting the cable's lifespan.
• Storage: When not in use, store the cable in a cool, dry place, ideally coiled loosely to prevent kinks.
• Cleaning: Gently wipe the cable and connectors with a dry, soft cloth if they become dirty. Avoid using liquids or abrasive cleaners.

Troubleshooting

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

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 into the device and monitor ports. Try reconnecting them.
2. Check Monitor Input Source: Use the monitor's On-Screen Display (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.

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. Swipe down the phone's notification panel to check for relevant prompts.
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.

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.

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.
