Troubleshooting HDMI Auto-Switch Issues 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.

To resolve this issue, we recommend trying the following:

• Use a shorter HDMI cable: A shorter cable, such as a 3.3ft cable, may provide a stronger signal and meet the requirements for automatic switching.
• Adjust BIOS configuration: Explore the BIOS settings of your NUC Mini PC to see if there are any options related to HDMI output or power management that could affect the auto-switch functionality.
• Try different output interfaces: Experiment with using different HDMI ports on your NUC Mini PC, such as HDMI 1 (recommended) or HDMI 2.

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

Please note that the majority of HDMI switches currently on the market are designed to detect HDMI 5V signals to activate the auto-switch function. However, we have not yet released high-end models that activate the automatic switching function based on HDMI video signal detection.

We understand this issue may be frustrating. While we are unable to conduct further testing without this specific model of Mini PC, we are committed to assisting you. If you have any further questions or concerns, please feel free to let us know. We will do our best to help you resolve the issue.

Thank you for your patience.
