- HDMI + USB-A (2 cable connection): If your laptop has 1 HDMI port + 1 USB-A port, use two cables: one USB-A to USB-C cable to connect the screen extender using one USB-A to Type-C cable + one HDMI to Mini HDMI cable.

5. Troubleshooting
If you encounter issues with your KEFEYA KX2, refer to the following common problems and solutions:
- No Signal / Unstable Signal:
- Ensure all cables (USB-C, HDMI, USB-A) are securely connected to both the screen extender and your device.
- If using HDMI + USB-A, confirm the USB-A cable is connected to a power source (e.g., external 5V/2A adapter) to power the screen extender.

- Try connecting to a different port on your laptop or another device to rule out port issues.
- Screen Does Not Light Up:
- Confirm the screen extender is receiving adequate power. Connect an external 5V/2A power adapter if your computer cannot provide enough power.
- Check the power button on the screen extender to ensure it's not accidentally turned off.
- Display Settings Issues (Resolution, Orientation):
- Adjust display settings directly on your computer's operating system (e.g., Windows Display Settings, MacOS Displays).
- Ensure the resolution is set to 1920x1080 for optimal clarity.
