7. Troubleshooting

If you encounter issues with your UANTIN Dual HDMI Adapter, refer to the following troubleshooting steps:

7.1 No Display / Monitors Not Detected

• Driver Check: Ensure the DisplayLink driver is correctly installed and updated. A common issue is the adapter not functioning without the required driver.
• Restart Computer: Sometimes a simple restart can resolve detection issues after driver installation.
• Cable Connections: Verify that all HDMI cables and the adapter's USB connector are securely plugged into both the monitors and the computer. Try re-plugging them.
• USB Port: If using a USB-C port, confirm it supports video output (DisplayPort Alt Mode or Thunderbolt). Try a different USB port if available.
• Monitor Input: Ensure your monitors are set to the correct HDMI input source.

7.2 Intermittent Display / Flickering

• Cable Quality: Use high-quality HDMI cables. Faulty or low-quality cables can cause signal issues.
• Resolution/Refresh Rate: Ensure the display resolution and refresh rate are supported by both your monitors and the adapter. Lowering the resolution might help if the issue persists.
• Heat: Excessive heat can sometimes lead to performance issues. Ensure the adapter is in a well-ventilated area.

7.3 Adapter Gets Hot During Use

• Normal Operation: It is normal for the adapter to become warm during operation, especially when driving two high-resolution displays. The aluminum casing is designed to dissipate this heat.
• Ventilation: Ensure the adapter is not covered and has sufficient airflow around it.
• Excessive Heat: If the adapter becomes uncomfortably hot to touch or causes system instability, disconnect it immediately and contact support.
