Resolución de problemas

If you encounter issues with your JTECH-4KCP capture card, refer to the following common troubleshooting steps:

Problema	Causa posible	Solución
No video signal on computer/software	Incorrect cable connection, incompatible resolution/refresh rate, software not configured.	Ensure all HDMI and USB cables are securely connected. Verify the HDMI source is outputting a signal (up to 4K@60Hz). Check your capture software settings to ensure the JTECH-4KCP is selected as the video source and configured for 1080p 60Hz capture. Restart your computer and the source device.
No audio captured or monitored	Incorrect audio connections, software audio settings.	Ensure external microphone/headphones are correctly plugged into the capture card. Check audio input/output settings in your capture software. Verify the source device is outputting audio via HDMI.
High latency or stuttering during capture/streaming	Computer performance issues, USB port issues, software settings.	Ensure your computer meets the minimum system requirements (Intel Core i5 or AMD equivalent, 4GB RAM). Connect the capture card to a USB 3.0 port directly on your computer, avoiding USB hubs if possible. Pecha as aplicacións innecesarias que se executan en segundo plano. Adjust capture software settings (e.g., lower bitrate, resolution if necessary).
Cannot capture certain content (e.g., movies)	HDCP (High-bandwidth Digital Content Protection) enabled.	The capture card respects HDCP. Content protected by HDCP cannot be captured or recorded. This is a standard digital rights management feature.
