5. Maintenance

5.1. Cleaning the Screen

To clean the screen, gently wipe it with a soft, lint-free cloth. For stubborn smudges, slightly dampen the cloth with water or a screen-safe cleaning solution. Avoid using harsh chemicals, abrasive materials, or excessive moisture, as these can damage the display.

5.2. Screen Protector

The monitor comes with a double-layer screen protector. You may remove the first protective film, but do not remove the second film, as it serves as the actual screen protector. Removing it will leave the screen completely unprotected and vulnerable to scratches and damage.

Figure 7: Double-Layer Screen Protection. This diagram visually explains the two layers of screen protection. The first layer is for product protection during shipping, while the second layer is the permanent screen protector that should not be removed.

6. Troubleshooting

• No Display/Black Screen:
  • Ensure the HDMI cable is securely connected to both the monitor and your device.
  • Verify that the USB power cable is properly connected and providing sufficient power. Try connecting both USB-A ends if only one is used.
  • Check if your device's display output is enabled and configured correctly (e.g., extended display, duplicate display).
• Touch Functionality Not Working:
  • Ensure the USB-C to Dual USB cable is fully connected to the monitor's USB-C port and the USB-A ends are connected to your device. This cable carries the touch data.
  • For Raspberry Pi, ensure your operating system (e.g., Raspbian) is configured to recognize the touch input. Specific drivers or configuration steps might be needed for certain OS versions.
  • For Windows, ensure the touch screen is recognized in Device Manager.
• Insufficient Brightness:
  • Ensure both USB-A connectors of the power cable are plugged into your device or a power adapter to provide maximum power.
  • Use the brightness adjustment button on the monitor to increase the brightness.
• Image Quality Issues (Blurry, Incorrect Resolution):
  • Ensure your device's display settings are configured to output at the monitor's native resolution of 1024x600 pixels.
  • Check the HDMI cable for any damage.
