3.1.1 USB-C Connection (Full-Featured)
For devices with a full-featured USB-C port (supporting video, power, and touch data), a single USB-C to USB-C cable can provide all necessary functions.
- Connect one end of the USB-C to USB-C cable to the monitor's full-featured USB-C port.
- Connect the other end to your device's full-featured USB-C port.
- The monitor should automatically detect the signal and power on. Touch functionality will be enabled.
Note:
- Ensure your device's USB-C port supports video output (DisplayPort Alternate Mode) and power delivery.
- If your device cannot provide sufficient power, connect the monitor to an external power source using the provided power adapter and USB-A to USB-C cable.
3.1.2 Mini HDMI Connection
For devices with an HDMI output, use the Mini HDMI port on the monitor. This connection requires a separate USB-C cable for power and touch functionality.
- Connect one end of the Mini HDMI to HDMI cable to the monitor's Mini HDMI port.
- Connect the other end to your device's HDMI port.
- Connect the USB-A to USB-C cable from the monitor's USB-C port to a power source (e.g., power adapter, laptop USB-A port, power bank).
- To enable touch functionality with an HDMI connection, you must also connect a USB-A to USB-C cable from your device's USB-A port to the monitor's USB-C port.
