3. Setup Guide
3.1 Powering the Monitor
The monitor can be powered in several ways:
- Via Power Adapter: Connect the provided power adapter to one of the Type-C ports (1 or 2) and plug it into a power outlet.
- Via USB-C from Device: If your connected device (e.g., laptop, smartphone) supports power delivery via its Type-C port, the monitor can draw power directly from it using a single USB-C to USB-C cable. Ensure the device can provide sufficient power.
- Via Power Bank: For portable use, connect a compatible power bank to one of the Type-C ports using the USB-A to USB-C power cable.
3.2 Connecting to Devices
The monitor supports various connection methods:
- USB Type-C Connection (Full-function):
- Ensure your device's USB-C port supports DisplayPort Alternate Mode (DP Alt Mode).
- Connect one end of the provided USB-C to USB-C cable to your device's USB-C port and the other end to either Type-C port (1 or 2) on the monitor.
- If your device cannot provide enough power, connect the monitor to an external power source using the power adapter or a power bank.

- HDMI Connection:
- Connect one end of the provided Mini HDMI to HDMI cable to the Mini HDMI port (3) on the monitor.
- Connect the other end of the HDMI cable to your device's HDMI port.
- Always connect the monitor to an external power source using the power adapter when using HDMI, as HDMI does not provide power.
- Gaming Consoles (PS4/PS5, XBOX, Switch):
Connect gaming consoles via the Mini HDMI port. Ensure the monitor is externally powered. For Nintendo Switch, a separate power source for the Switch is also required, and a full-function Type-C cable can be used if the Switch supports video output via Type-C.
