Troubleshooting HDMI Switch Auto-Switch Issue with NUC7CJYH Mini PC

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

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 like HDMI 1 (recommended) or HDMI 2. Unfortunately, since we do not have this specific model of Mini PC, we are unable to conduct further testing.

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

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.
