2.2 Initial Setup and Connections
Follow these steps to connect your monitor:

- Power Connection: Connect the power supply to the monitor using the provided USB-C cable and power adapter. This is crucial for proper operation.
- Video Input: Choose your preferred connection method:
- USB-C (Full-Featured): If your device (laptop, phone, game console) supports video output via USB-C (DisplayPort Alternate Mode), connect one end of the USB-C to USB-C cable to the monitor's full-featured USB-C port and the other end to your device. This single cable can provide both power and video.
- Mini HDMI: Connect one end of the Mini HDMI to HDMI cable to the monitor's Mini HDMI port and the other end to your device's HDMI port. If using HDMI, ensure the monitor is also powered via a separate USB-C power connection.
- Audio Output: The monitor has built-in speakers. For external audio, connect headphones or external speakers to the 3.5mm audio jack.
Note:
- To achieve 120Hz refresh rate when connected via HDMI, you may need to select a lower resolution, as the refresh rate is typically 100Hz at 2880x1800 resolution via HDMI. Type-C connections are unaffected.
- This is the non-touch version of the monitor.
