2.2 Connecting the Monitor
The NGTeco N3 monitor supports two primary connection methods:
Option 1: USB Type-C (Full-Featured)
If your device (laptop, phone, etc.) has a full-featured USB-C port that supports video output and power delivery, you can connect the monitor with a single USB-C to USB-C cable.
- Connect one end of the USB-C to USB-C cable to your device's USB-C port.
- Connect the other end to the monitor's USB-C port.
- The monitor should automatically detect the signal and power on.
Option 2: HDMI and Power Cable
If your device does not have a full-featured USB-C port, or if you prefer HDMI, you will need both an HDMI cable for video and a USB cable for power.
- Connect the HDMI to Type-C cable from your device's HDMI port to the monitor's HDMI port.
- Connect the USB-A to USB-C cable from a power source (e.g., wall adapter, laptop USB-A port) to the monitor's USB-C power input port.
- The monitor will power on and display the signal from the HDMI input.

2.3 Compatibility Notes for MacBooks (M1/M2/M3 Chips)
For MacBooks equipped with M1, M2, or M3 chips, dual-screen functionality may require an H5 hub (if not included) and specific driver installation. If you encounter issues with one screen working, no signal, or screen flickering, these are often compatibility-related and can be resolved by ensuring proper drivers and accessories are used. Please refer to NGTeco Support for detailed instructions and assistance.
2.4 Using the Detachable Stand
The monitor includes a detachable stand for flexible positioning. The stand allows for 360-degree rotation and adjustable angles for both horizontal (25-80 degrees) and vertical (20-89 degrees) display modes. You may hear a gear sound when adjusting the bracket, which is normal.

4. Maintenance
Proper care ensures the longevity and performance of your NGTeco N3 Portable Monitor.
4.1 Cleaning the Screen
- Always power off the monitor and disconnect it from the power source before cleaning.

- For stubborn marks, lightly dampen the cloth with water or a screen-specific cleaning solution. Do not spray liquid directly onto the screen.
- Avoid using harsh chemicals, abrasive cleaners, or alcohol-based solutions, as these can damage the screen coating.

5. Troubleshooting
If you encounter issues with your NGTeco N3 Portable Monitor, refer to the following common solutions:
5.1 No Signal / Black Screen

5.2 Screen Flickering / Unstable Display

5.4 One Screen Working (for dual-screen setups)
- MacBook M1/M2/M3: As noted in the setup section, specific hubs and drivers may be required for dual-screen functionality on these MacBooks.
- Display Settings: Ensure your operating system's display settings are configured to 'Extend' or 'Duplicate' displays, and that both monitors are detected.
