Jetson Xavier nx Screen is not displaying (HDMI Port)

I am using Jetson Xavier nx and latest version of jetpack of Xavier nx . I have connected the Xavier nx to LED screen through HDMI cable but it was displaying the screen for 3-4mins and then displays black screen but it is not displaying the screen, just showing black screen. My HDMI cable is working fine. I have checked it by connecting to other devices.

So please tell me how to resolve this issue as soon as possible.

Maybe you can describe your problem more clearly first so that other people can resolve your problem as soon as possible.

  1. Is this a custom board of NX devkit?

  2. You said “it was displaying the screen for 3-4mins”, so the display was fine? Can you check if the monitor is going to power saving?
