Connecting Your Monitor

The monitor supports both single-cable and dual-cable connections, depending on your device's capabilities.

Single Cable Connection (USB-C)

For devices with a full-featured USB-C port (supporting Thunderbolt 3.0/4.0 or USB 3.1 DisplayPort Alt Mode), a single USB-C to USB-C cable can transmit both video, audio, and power.

  1. Connect one end of the USB-C to USB-C cable to the monitor's full-featured USB-C port.
  2. Connect the other end to your device's full-featured USB-C port.
  3. The monitor should automatically power on and display your device's screen.

Dual Cable Connection (Mini HDMI + USB-C for Power)

For devices without a full-featured USB-C port, or if additional power is required, use the Mini HDMI and a separate USB-C power cable.

  1. Connect one end of the Standard HDMI to Mini HDMI cable to the monitor's Mini HDMI port.
  2. Connect the other end to your device's HDMI port.
  3. Connect the USB-A to USB-C cable (or USB-C to USB-C cable) to the monitor's power-only USB-C port and the other end to the provided 5V/3A power adapter or a powered USB-A/USB-C port on your device.
  4. Ensure the power adapter is plugged into a wall outlet.
