Display Issue in Jetson Nano Board

I connected the Jetson Nano board to the monitor using an HDMI to HDMI cable. At this time, the board’s power was connected to 5V 4A instead of USB using a power cable. When I connected the power, the green light on the board turned on, but the monitor said that it could not receive the signal. Why is this happening? Can I solve it?

This is because the screen does not change whether I connect it to the SD card or not, and the cable and monitor work fine when connected to another PC.

Basically you should dump the log first. There won’t be any solution before checking the log.
