Troubleshooting HDMI Auto-Switch Issues on NUC7CJYH Mini PC

Thank you for providing us with the information. Our engineers have analyzed the issue and it appears that the NUC Mini PC NUC7CJYH HDMI Port's low-power design may not be supplying sufficient 5V voltage signals to activate the HDMI switch auto-switch function.

To resolve this issue, we recommend trying a shorter HDMI cable, such as a 3.3ft cable, to see if it meets the requirements for automatic switching. Additionally, you can try adjusting the BIOS configuration and using different output interfaces on the NUC Mini PC, such as HDMI 1 (recommended) or HDMI 2. However, please note that since we do not have this specific model of Mini PC, we are unable to conduct further testing.

For your reference, I have attached the technical product specification for your NUC Mini PC NUC7CJYH to this email.

If you have any further questions or concerns, please feel free to let us know. We will do our best to assist you in resolving the issue.

Thank you for your patience.
