3.1 System Compatibility
This HotYeah triple monitor is exclusively designed for Windows system laptops. A single USB-C cable connection is possible if your device features a full-function USB-C port. Each screen can be independently adjusted for brightness, RGB, and other settings. For phone and tablet connections, only mirror mode is supported.
3.2 True Plug and Play
No driver installation or additional applications are required for Windows systems. The monitor features two full-function USB Type-C ports, allowing a single USB-C cable to control both screens simultaneously, reducing cable clutter.

4. Setup Guide
4.1 Windows Laptop Connection (Full-function Type-C Port)

- Connect one end of the USB-C to USB-C cable to your laptop's full-function Type-C port.
- Connect the other end of the USB-C to USB-C cable to one of the full-function Type-C ports on the HotYeah monitor.
- The monitor should automatically power on and display an extended desktop.
- If the screen flickers or only one screen lights up, connect the power adapter to the monitor's second USB-C port for additional power.
