For devices with a full-featured USB-C port (supporting DisplayPort Alternate Mode and Power Delivery), a single USB-C to USB-C cable can transmit both video and power.
- Connect one end of the provided USB-C to USB-C cable to a full-featured USB-C port on your laptop or smartphone.
- Connect the other end of the USB-C to USB-C cable to either USB-C port on the KOORUI monitor.
- The monitor should automatically detect the signal and power on.

2. Connecting via HDMI and USB-C (for Power)
If your device does not have a full-featured USB-C port or if you are connecting to a gaming console or desktop PC, use an HDMI cable for video and a USB-C cable for power.
- Connect one end of the provided HDMI cable to the HDMI port on your device (e.g., laptop, game console).
- Connect the other end of the HDMI cable to the HDMI port on the KOORUI monitor.
- Connect the provided USB-A to USB-C power cable to a USB power adapter (not included) or a powered USB-A port on your device.
- Connect the USB-C end of the power cable to one of the USB-C ports on the KOORUI monitor to supply power.
- The monitor should power on and display the video signal.

3. USB-C Port Compatibility
When using a single USB-C cable for connection, ensure your device's USB-C port supports video output (DisplayPort Alternate Mode) and power delivery. Not all USB-C ports are full-featured.
