Setup Instructions
Follow these steps to set up your Lemorele TC550 USB-C 7-in-1 Dual Display Docking Station:
- Verify Host Device Compatibility: Ensure your laptop's USB-C port supports DisplayPort Alt Mode. Refer to your laptop's specifications or the image below for common USB-C port types.

Image: USB-C Port Compatibility Guide. This diagram illustrates which types of USB-C ports on your laptop support DisplayPort Alt Mode, which is essential for video output. Compatible ports include Thunderbolt 3/4, Data+DisplayPort Alt, and Data+PD DisplayPort Alt. Ports that only support data transfer, charging, or data+power delivery without DisplayPort Alt are not suitable for video output through this docking station.
- Connect the Docking Station: Plug the USB-C cable of the docking station into a compatible USB-C port on your laptop.

- Connect External Displays:
- For the first external display, connect an HDMI cable from your monitor to the HDMI port on the docking station.
- For the second external display, connect a USB-C to DisplayPort cable (or a compatible USB-C cable for DP Alt Mode) from your monitor to the USB-C DP port on the docking station.

Image: Dual Display Setup. This image illustrates a laptop connected to two external monitors using the docking station. One monitor is connected via HDMI, and the other via USB-C DisplayPort, demonstrating the dual display capability.
- Connect Power (Optional but Recommended): For stable operation and to charge your laptop, connect your laptop's USB-C power adapter to the USB-C PD Input port on the docking station.
- Connect USB Peripherals: Plug your USB devices (e.g., keyboard, mouse, external hard drive) into the available USB-A 3.0 or USB-A 2.0 data ports.
Operating Instructions
Once the docking station is set up, you can begin using its various functions.
- Dual Display Configuration:
- Windows Systems: Supports various display modes including mirrored (showing the same content on all screens) and extended (allowing different content on each screen, creating a larger workspace). You can configure these settings in your display settings.
- macOS Systems: Supports mirrored (AAA) mode, where all displays show the same content, or extended (ABB) mode, where the laptop screen is one display and both external monitors mirror each other. macOS does not support Multi-Stream Transport (MST) for three distinct extended displays (ABC).

Image: Multiple Display Modes. This diagram visually explains the different display configurations available for Windows and macOS users. It shows that Windows supports mirrored (AAA), extended (ABB), and triple extended (ABC) modes, while macOS is limited to mirrored (AAA) and extended (ABB) modes, with the external displays mirroring each other.
- Data Transfer: Use the blue USB-A 3.0 port for connecting devices requiring high-speed data transfer, such as external SSDs or flash drives, at up to 5Gbps. The three black USB-A 2.0 ports are suitable for standard peripherals like keyboards, mice, and printers.

Image: Fast Data Transfer and PD Charging. This image demonstrates the docking station's capabilities for quick data transfer via the 5Gbps USB-A 3.0 port and efficient laptop charging through the 100W USB-C Power Delivery port.
- Power Delivery: If your laptop supports USB-C Power Delivery, connecting your laptop's power adapter to the docking station's USB-C PD port will charge your laptop at up to 85W. This allows you to power your laptop and use the docking station with a single connection.
