3.2 Connecting to Devices
The BIGASUO portable monitor offers versatile connectivity options. Ensure your device has sufficient power or connect the included AC adapter to the monitor's DC-5V port for stable operation.

Note: When powered solely by the Type-C cable, the screen brightness may be reduced by half. For optimal brightness, connect the AC adapter.

For devices using Mini-HDMI, you will need to connect both the Mini-HDMI to HDMI cable for video and a Type-C to USB cable (or AC adapter) for power.
