4.2 Windows Display Configuration
For Windows operating systems, the adapter supports Mirror Mode, Extend Mode (SST), and Extend Mode (MST).
- Mirror Mode (A-A-A): All displays show the same content.
- Extend Mode (SST - A-B-B): The laptop display (A) is extended, and both external monitors (B) mirror each other, showing different content from the laptop.
- Extend Mode (MST - A-B-C): The laptop display (A) is extended, and both external monitors (B and C) display independent content, creating a triple-display setup.

4.3 macOS Display Configuration
Due to macOS limitations, all MacBook models can only mirror the display on two screens (A-A-A / A-B-B) and cannot support MST (Multi-Stream Transport) mode (A-B-C). Both external monitors will display the same content.
- Mirror Mode (A-A-A): All displays show the same content.
- Extend Mode (SST - A-B-B): The laptop display (A) is extended, and both external monitors (B) mirror each other, showing different content from the laptop.

7. Troubleshooting
If you encounter issues with your Newmight USB C to Dual HDMI Adapter, please refer to the following troubleshooting tips:
- No Display/Intermittent Connection:

- Try connecting the adapter to a different USB-C port on your host device.

- Restart your host device.
- Incorrect Resolution/Display Mode:
- Adjust display settings in your operating system (e.g., Windows Display Settings or macOS System Settings > Displays).

- Adapter Overheating:
- The aluminum alloy design aids in heat dissipation, but ensure adequate airflow around the adapter. Avoid covering it.
