Operating Instructions
Multi-Monitor Display Configuration
The docking station supports various display modes depending on your operating system.
For Windows Systems (DP1.4 Compatible Laptops):
- Mirror Mode: Displays the same content on all connected monitors and the laptop screen.
- Extend Mode: Extends your desktop across multiple monitors, allowing for increased workspace.
- MST (Multi-Stream Transport) Extend Mode: For triple screen setups, allowing different content on each external monitor (B, C, D) in addition to the laptop screen (A).

Image: A visual guide demonstrating Mirror Mode, Extend Mode, and MST Extend Mode for Windows laptops connected to the docking station, showing how content is displayed across the laptop screen and up to three external monitors.
For macOS Systems (DP1.4 Compatible Laptops):
- Mirror Mode: Displays the same content on all connected monitors and the laptop screen.
- Extend Mode: Extends your desktop across multiple monitors. Note that macOS typically mirrors the extended display across all external monitors when multiple are connected via a single MST hub.
- Important Note: macOS systems do not support MST Extend mode for displaying different content on each external monitor. All external monitors will display mirrored content in extend mode.

Data Transfer and Charging
- USB 3.1 Ports: Use the USB A 3.1 and USB C 3.1 ports for high-speed data transfer (up to 10Gbps) with compatible devices like external SSDs or flash drives.
- USB 2.0 Ports: Ideal for connecting peripherals such as keyboards, mice, or printers.
- SD/Micro SD Slots: Insert memory cards for quick data access and transfer (up to 104 MB/s).
- Power Delivery: When a compatible USB-C power adapter is connected to the PD port, the docking station will pass through up to 100W to charge your connected laptop.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the docking station. Avoid liquid cleaners or abrasive materials.
- Storage: Store the docking station in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Care: Avoid bending or twisting the integrated USB-C cable excessively to prevent internal damage.
- Ventilation: Ensure the docking station has adequate ventilation to prevent overheating, especially during prolonged use with multiple connected devices.
Troubleshooting
- No display on external monitors:
- Ensure your laptop's USB-C port supports DisplayPort Alt Mode. Not all USB-C ports support video output.
- Check all HDMI cable connections between the docking station and monitors.
- Verify that the monitors are set to the correct input source (HDMI 1, HDMI 2, etc.).
- Try connecting one monitor at a time to isolate the issue.
- Restart your laptop.
- For macOS, remember that MST Extend mode (different content on each external monitor) is not supported.
- Laptop not charging:
- Ensure your laptop's original USB-C power adapter is connected to the PD port on the docking station.
- Verify the power adapter is functioning correctly and provides sufficient wattage (e.g., 65W or higher).
- Check the USB-C connection between the docking station and your laptop.
- USB devices not recognized or slow data transfer:
- Ensure the devices are properly plugged into the correct USB ports.
- For high-speed devices, use the USB 3.1 ports.
- Try connecting the device directly to your laptop to confirm it functions independently.
- Some high-power USB devices may require external power if the docking station's power delivery is insufficient or not connected.
- No internet connection via Ethernet:
- Check the Ethernet cable connection to both the docking station and your router/modem.
- Verify that your router/modem is working and providing an internet connection.
- Ensure your laptop's network settings are configured to use the wired Ethernet connection.
