When I connected nx and my display with hdmi cable, I only got a black screen. But after I inserted the mouse, the mouse was on, indicating that my system started successfully.But the screen is still black.

Is it possible that nx must use hdmi 2 instead of hdmi 1？

Hi,

We need to check the kernel log to know what is going on.

Generally, if you cannot see the monitor, you need to use the serial console to operate the system.
