7. Troubleshooting
If you encounter issues with your StreamLine MINI+ GC311G2, refer to the following common solutions.
7.1 No Video Signal
- Check Connections: Ensure all HDMI and USB cables are securely connected to the correct ports on the capture card, source device, and computer/display.
- Source Output: Verify that your source device (console, PC) is powered on and outputting video correctly to your display. Try connecting the source directly to the display to confirm it's working.
- Software Recognition: Confirm that the capture card is recognized in your streaming/recording software (e.g., OBS Studio, AVerMedia Streaming Center). If not, try restarting the software or your computer.
- Resolution/Refresh Rate: Some older displays or software may not support certain resolutions or refresh rates. Try lowering the output resolution from your source device or within your capture software.
7.2 No Audio
- Audio Settings in Software: In your streaming/recording software, ensure the audio input for the capture card is correctly configured and not muted. For OBS, set the audio monitoring to "Monitor and Output".
- System Audio: Check your computer's sound settings to ensure the correct playback device is selected and volume levels are adequate.
- Source Audio: Verify that your source device is outputting audio via HDMI.
7.3 Lag or Stuttering Video
- USB Port: Ensure the capture card is connected to a USB 3.0 (or higher) port on your computer. USB 2.0 ports have insufficient bandwidth for high-resolution/frame rate capture.
- System Performance: Close any unnecessary applications running in the background. Ensure your computer's CPU and GPU are not overloaded.
- Software Settings: Reduce the capture resolution or frame rate in your software. Try different video formats (NV12, YUY2, MJPEG) to see if one performs better.
- Cable Quality: Use high-quality HDMI cables, especially for 4K signals.
