3. Operating Instructions
3.1 Dual HDMI Display Output
The hub supports dual HDMI display output, allowing you to extend or mirror your screen to two external monitors. The maximum resolution and refresh rate depend on your host device's DisplayPort (DP) version and operating system.
- macOS: Supports Mirror Mode (A+A+A) and Extend Mode (A+B+B). macOS does not support Multi-Stream Transport (MST) for independent extended displays.
- Windows OS: Supports Mirror Mode (A+A+A) and Extend Mode (A+B+C or A+B+B).
Note: Dual HDMI output is not supported on devices with Apple M1/M2/M3 chipsets due to hardware limitations. For these chipsets, only one external display is supported.

4. Maintenance
- Cleaning: Use a soft, dry cloth to clean the hub. Avoid liquid cleaners or abrasive materials.
- Storage: Store the hub in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Do not attempt to disassemble or repair the hub yourself.
- Heat Management: It is normal for the hub to become warm during extended use, especially when multiple high-power devices or displays are connected. Ensure adequate airflow around the hub to prevent overheating.
5. Troubleshooting
- No Display Output:
- Ensure your host device's USB-C port supports DisplayPort Alt Mode.
- Verify that HDMI cables are securely connected to both the hub and the monitors.
- Check monitor input settings to ensure the correct HDMI input is selected.
- For macOS, remember that M1/M2/M3 chipsets only support one external display.
- Try restarting your host device and reconnecting the hub.
- Intermittent Display or Flickering:
- Ensure the hub is receiving sufficient power, especially if multiple devices are connected. Connect a power adapter to the PD port.
- Reduce the number of connected peripherals if the hub is getting excessively hot.
- Ensure your HDMI cables are of good quality and support the desired resolution/refresh rate.
- Update graphics drivers on your host device.
- USB Devices Not Recognized or Slow Data Transfer:
- Ensure the hub is connected firmly to your host device.
- For optimal speed, use the USB 3.0 ports for high-speed devices.
- If connecting a high-power USB device (e.g., external HDD), ensure the hub is connected to a power adapter via its PD port.
- Try connecting the USB device directly to your host device to rule out device issues.
- No Ethernet Connection:
- Verify the Ethernet cable is securely connected to both the hub and your router/modem.
- Check network settings on your host device.
- Ensure your router/modem is functioning correctly.
- Hub Gets Warm:
- It is normal for the hub to generate heat during operation, especially when driving dual 4K displays or charging your laptop.
