Setup
Follow these steps to set up your FOPO Laptop Screen Extender:
1. Driver Installation:
Before connecting the monitors, install the necessary driver. The driver is provided on the included U Disk. For Windows 10/11 systems, the driver may install automatically if your laptop is connected to the internet.

- Locate and double-click the driver application (e.g., "BaseDisplayDriver_XXXX.X.exe") to begin installation.
- Follow the on-screen prompts to complete the driver installation. A system restart may be required.
2. Physical Connection:
The FOPO S688 supports two main connection methods:
Method 1: Using USB-C to USB-C Cable (for laptops with USB-C interface)
- Connect one end of the provided USB-C to USB-C cable to the USB-C port on the FOPO extender.
- Connect the other end of the USB-C to USB-C cable to an available USB-C port on your laptop.
- Note: If your laptop's USB-C port does not supply sufficient power (less than 10W), you may need to connect an external power supply to the FOPO extender's dedicated power-only USB-C port.
Method 2: Using Dual USB-A to USB-C Cable (for laptops with 2 USB-A ports)
