4.2 Connecting to Devices
The monitor supports various connection methods:
- USB Type-C Connection (Single Cable): If your smartphone or computer supports Thunderbolt 3 or USB 3.1 Gen2 protocol, you can connect it to the monitor using a single Type-C to Type-C cable for both video signal, touch functionality, and power.
- HDMI + USB Type-C Connection: For devices with an HDMI output, connect the Mini HD cable for video. For touch functionality, connect the USB to Type-C cable from your device to the monitor's full-function Type-C port. Ensure the monitor is also powered via the PD adapter.
Note: If your smartphone does not support USB 3.1, touch operation may not function.

6. Maintenance
- Cleaning: Use a soft, lint-free cloth to clean the screen. For stubborn smudges, lightly dampen the cloth with water or a screen-safe cleaner. Avoid harsh chemicals.
- Storage: When not in use, store the monitor in its protective case to prevent scratches and damage.
- Handling: Handle the monitor with care to avoid dropping or impacting it, which could damage the screen or internal components.
7. Troubleshooting
- No Display/Power: Ensure the PD power adapter is securely connected and providing sufficient power. Check all cable connections.
- No Touch Functionality: Verify that your connected device (smartphone/PC) supports Thunderbolt 3 or USB 3.1 Gen2 protocol for touch via Type-C. If using HDMI, ensure the USB to Type-C cable is also connected for touch data.
- Screen Brightness Too Low: The monitor's brightness may default to minimum after power-up. Adjust it manually using the OSD menu buttons.
- Image Distortion/Incorrect Aspect Ratio: Check your device's display settings to ensure the resolution is set correctly (1920x1280). Some devices may output 16:9, which could result in black bars or stretched images on the 3:2 monitor.
- No Audio: If using a single Type-C cable, audio may output from the source device. If using HDMI, ensure the monitor's volume is turned up or connect headphones to the 3.5mm jack.
