No display after kernel boot

Out of the box I hooked up my new Orin AGX to a Dell native displayport monitor, keyboard, mouse, and power. The monitor would show the boot BIOS screen, but once OS boot started, monitor would go black and into standby power. I could navigate the BIOS settings. But every boot attempt left me without a display. It was like there was no OS loaded.
I was able to dataload latest kernel. Now the kernel boot log quickly scrolls up the screen after the BIOS screen. It gets to the end where I’d expect it to switch to graphical mode, and the screen goes black.

I tried connecting to the serial port on microUSB but am not getting anything. dmesg shows it hooking up to /dev/ttyUSB0. I run minicom -D /dev/ttyUSB0 and it just says “offline”, with no data coming through even during a reboot.

I tried hooking the displayport output to another newer Dell 4k monitor, exact same behavior.

I got it working. SSH has starting working somewhere along the way. Tried running xrandr to see what was going on and it told me to run “unminimize”, so did that. That triggered a BUNCH of package updates. Restarted and got my display.
Why don’t these things come with running software preloaded?

Did you really flash the board in the begging when you get it out of the box?

As best I could tell, I had to. It would start at BIOS, then when it would have normally started booting the kernel, screen went black and eventually shut off. Not until I flashed it did the kernel boot process show after BIOS.
