3. Setup Guide
Follow these steps to set up your USB C Docking Station:
- Verify Laptop's USB-C Port: Ensure your laptop's USB-C port supports video output (DisplayPort Alt Mode) and/or power delivery. The docking station requires a Thunderbolt 3/4 or a full-featured USB-C port. If your USB-C port only supports data or charging, video output will not function.

- Connect to Laptop: Plug the USB-C connector of the docking station into a compatible USB-C port on your laptop.
- Connect External Monitors: Use HDMI cables to connect your monitors to the HDMI ports on the docking station.
- Connect Power Adapter (Optional but Recommended): For optimal performance and to charge your laptop, connect your laptop's original USB-C power adapter to the PD (Power Delivery) port on the docking station. A 100W PD charger and USB-C to C cable are required to achieve 85W charging output.

4. Operating Instructions
4.1 Display Modes
The docking station supports different display modes depending on your operating system:
For Windows Laptops (MST Mode)
Windows laptops support Multi-Stream Transport (MST) mode, allowing you to extend your desktop across two external monitors, or mirror your display.

To configure display settings on Windows:
- Right-click on your desktop and select "Display settings".
- Under "Multiple displays", choose your preferred option (e.g., "Extend these displays" or "Duplicate these displays").
For macOS Laptops (SST/Mirror Mode Only)
Due to macOS system limitations, this docking station only supports Single-Stream Transport (SST) or Mirror Mode. This means both external monitors will display the same content, which can either mirror your MacBook's display or extend it as a single, duplicated external display.

To configure display settings on macOS:
- Go to "System Settings" (or "System Preferences") > "Displays".
- Select "Arrangement" to configure your displays. You will see options for mirroring.
4.2 Data Transfer
The USB 3.0 ports (Type-A and Type-C) and the SD/TF card slots allow for high-speed data transfer. Simply plug in your USB devices or insert your memory cards to access and transfer files.
