4. Setup
Follow these steps to set up your KOORUI portable monitor:

- Power On: Press and hold the power button (usually located on the side) for approximately 3 seconds to turn on the monitor.
- Connect to Device:
- Single USB-C Connection (for compatible devices): Connect one end of the provided Type-C cable to the monitor's USB-C port and the other end to a full-featured USB-C port on your laptop, smartphone, or other compatible device. This single cable can transmit power, video, and data.
- Dual Cable Connection (USB-C for power + Mini-HDMI for video): If your device does not support full-featured USB-C, or if you require maximum brightness, use the Mini-HDMI port for video input. In this setup, you will also need to connect a USB-C cable to the monitor for power, ensuring it's connected to an external power supply (e.g., a wall adapter with 5V/2.0A or above).
