You can typically switch between these modes through your computer's display settings (e.g., Windows Display Settings or macOS System Preferences).
5.2 Low Latency Streaming
The TIMBOOTECH system utilizes advanced 5G technology to achieve ultra-low latency of approximately 0.1 seconds, ensuring a smooth and synchronized video and audio experience.

6. Advanced Features
