8. Troubleshooting
If you encounter issues with your AVMATRIX SD1242-4K, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No video output on displays. | Loose HDMI cables, incorrect EDID setting, power issue. | Check all HDMI cable connections. Ensure the splitter is powered on. Try different EDID modes (Auto or Standard). Test with a different HDMI source or display. |
| Video flickering or unstable image. | Poor quality HDMI cables, signal interference, EDID mismatch. | Use certified high-speed HDMI 2.0 cables. Ensure cables are not excessively long. Adjust EDID settings. Reduce cable length if possible. |
| Displays show different resolutions. | EDID setting not optimized for all displays. | Use EDID Copy mode from the lowest resolution display or a custom EDID that all displays can support. |
| Device not powering on. | Power adapter not connected, faulty power source. | Verify power adapter is securely connected to both the splitter and a working power outlet. Try the USB-C power option if DC fails, or vice-versa. |
