- Storage: When not in use, store the components in a dry, dust-free environment, ideally in their original packaging or a protective enclosure.
6. Troubleshooting
If you encounter issues, refer to the following common problems and solutions.
- No Display/Black Screen:
- Ensure the USB-C power adapter is correctly connected and providing sufficient power.
- Verify that the USB-C signal cable is securely connected to both the controller board and the source device.
- Check the signal output settings on your source device (PC/laptop) to ensure it is configured to output to an external display.
- Confirm that the ribbon cables connecting the LCD panel to the controller board are properly seated and not damaged.
- "USB-C not compatible with Windows" (as reported by some users):
- While the USB-C port is designed for signal input, some Windows systems may require specific drivers or configurations for display output over USB-C. Ensure your graphics drivers are up to date.
- Test with another USB-C enabled device or operating system if possible to isolate the issue.
- Consult your PC/laptop manufacturer's support for USB-C display output compatibility and driver information.
- Image Distortion or Flickering:
- Check the signal cable for damage or loose connections.
- Ensure the resolution and refresh rate settings on your source device are compatible with the display's specifications (2400x900).
- Try adjusting the display settings via the OSD menu.
- No Audio:
- Verify that external speakers are correctly connected to the audio output port on the controller board.
