4. Operating Instructions
4.1. Power Delivery (PD) Function
The USB-C PD port supports up to 100W power input. When a compatible USB-C power adapter is connected to this port, the docking station will pass through power to charge your host laptop. The actual charging speed depends on your laptop's power requirements and the power adapter's output.

4.2. Data Transfer
Utilize the various USB ports and card reader slots for efficient data transfer:
- USB 3.2 Gen 2 Type-A & Type-C: These ports offer data transfer speeds of up to 10Gbps, ideal for connecting high-speed external storage devices.
- USB 3.0 Type-A: Provides data transfer speeds of up to 5Gbps, suitable for most standard USB peripherals.
- SD/TF Card Readers: Supports UHS-I mode with transfer speeds up to 104MB/s, allowing for quick access to photos and videos from your memory cards.

4.3. Network Connection
The RJ45 Gigabit Ethernet port automatically adapts to 10/100/1000Mbps networks, providing a stable and reliable internet connection, which is often faster and more secure than Wi-Fi, especially in areas with poor wireless signal.
5. Display Modes
The docking station supports dual video output via HDMI and DisplayPort. The behavior of multiple displays varies depending on the operating system of your host device.
5.1. Windows OS (MST Support)
For Windows operating systems, the docking station supports Multi-Stream Transport (MST), allowing for both extended desktop and mirrored display modes across multiple monitors. You can connect two external monitors, and depending on your settings, they can display different content (extended) or the same content (mirror).
- Extended Desktop Mode: Your laptop screen (A) can be extended to two external monitors (B and C), allowing for a multi-tasking workspace.
- Mirror Mode: Your laptop screen (A) can be mirrored to both external monitors (A and A), displaying the same content on all screens.
5.2. Mac OS (No MST Support)
Mac OS does not support Multi-Stream Transport (MST). When connecting multiple external monitors to the docking station with a Mac OS device, all external monitors will display the same mirrored content. You can extend your desktop from your Mac to one external monitor, and any additional external monitors will mirror that extended display.
- Mirror Mode: Your MacBook screen (A) can be extended to one external monitor (B), and any other external monitor will mirror the content of monitor B. Alternatively, all external monitors can mirror the MacBook screen (A).
5.3. Resolution
Both HDMI and DisplayPort outputs support resolutions up to 3840x2160@60Hz. The actual resolution may vary based on your host device's capabilities and the connected monitors.
