7. Troubleshooting

- Try connecting the HDMI source directly to a display to confirm the source and display are working independently.
- Test with different HDMI cables, as faulty cables can cause signal loss.
- Poor Video Quality or Flickering:
- Ensure you are using high-quality HDMI cables, especially for 4K resolutions and longer distances.
- Check the resolution settings on your source device. Ensure it is compatible with your displays and the splitter.
- Verify that the total cable length (source to splitter + splitter to display) does not exceed the recommended maximum for your resolution.
- Audio Issues:
- Confirm that the audio settings on your source device are correctly configured.
- Ensure your displays are capable of playing the audio format being sent by the source.
