When using the general version of the AGX Xavier module on the customer board, the DP has normal output, but if the AGX Xavier Industrial module is replaced, the DP has no screen output. How to solve this problem?

Please disable unnecessary usb design because the default DP setting on NV devkit is bounded with usb type C.

Do you mean to disable the setting mentioned in this website?[https://forums.developer.nvidia.com/t/how-the-enable-2nd-hdmi-port-with-the-xavier/67906/14](https://forums.developer.nvidia.com/t/how-the-enable-2nd-hdmi-port-with-the-xavier/67906/14)  
My question is why using the same hardware and programs with different modules (industrial version and non-industrial version) will produce different results?

Hi,

They are not same program. The device tree in use are different.

Sort of. You could try it first.  
did you ever configure any device tree related things before?

So you side “The device tree in use are different”  
Where does it mean? Can you tell me?

As stated on this website, it has been modified in the program. Before posting this question.
