3.2 Connecting the Cables

The domyfan S1 monitor extender supports plug-and-play functionality, typically requiring only one cable for both power and video signal. Ensure your laptop has the necessary ports.

• USB-C Connection: If your laptop has a full-featured USB-C port (which supports video output and power delivery), use the provided USB-C to USB-C cable. Connect one end to your laptop's USB-C port and the other to the monitor extender's USB-C port.
• HDMI & USB-A Connection: If your laptop does not have a full-featured USB-C port, or if the USB-C port only supports power supply, you will need to use both the HDMI and USB-A cables. Connect the HDMI cable from your laptop's HDMI port to the monitor extender's HDMI input. Then, connect the USB-A to USB-C cable from your laptop's USB-A port to the monitor extender's USB-C port for power.

4. Operating Modes

The domyfan S1 monitor extender supports three primary display modes to suit various tasks:

• Extended Mode: This mode expands your desktop across both screens, allowing you to view different content on each display. This is ideal for multitasking, such as having a document open on one screen and a web browser on the other.
• Duplicated Mode: This mode mirrors the content of your primary laptop screen onto the extender. It is useful for presentations or sharing your screen with others.
• Second Screen Mode: This mode uses only the extender as the primary display, with the laptop screen turned off.

You can typically switch between these modes through your operating system's display settings (e.g., Windows Display Settings or macOS System Settings > Displays).

7. Troubleshooting

If you encounter issues with your domyfan S1 monitor extender, please refer to the following common troubleshooting steps:

7.1 "No Signal" Message with USB-C Connection

• If you connect via a USB-C cable and the screen displays "No Signal", it indicates that your laptop's USB-C port may only support power supply and not video output.
• Solution: In this scenario, you will need to connect an HDMI cable from your laptop to the monitor extender for video signals, in addition to the USB-C cable for power. This means one side of the screen will require two cables.

7.2 Connection Issues with HDMI + USB-A

• If you are using the HDMI + USB-A cable combination and one side of the screen does not work properly, or the port connection on the back of the expansion screen flashes red:
• Solution: Ensure the HDMI cable is connected to the correct port (typically the third port from top to bottom on the extender). If the issue persists, try removing the HDMI cable and re-plugging it firmly.

7.3 General Connection Failures

• Ensure all cables are securely connected to both the laptop and the monitor extender.
• Verify that your laptop's display settings are configured correctly for multiple monitors (e.g., detecting the new display, setting the correct resolution).
• Try restarting your laptop with the extender connected.
• If issues persist, please refer to the Warranty and Support section for further assistance.
