Jetson Orin NX no video output over HDMI

Product support

Hello

I have successfully build jeston-flash repo and flashed the orin nx but it seems that it doesnt output anything on screen through HDMI.
I tried 3 different carrier boards (j401,antmicro orin, nvidia xavier nx carrier board ) all with the same results.
No valid video output (or better yet on one monitor we got an output of 1280x1024@21hz !?)
Not even the Nvidia boot logo show up after flashing the orin using jetson-flash.
We also tried to set a resolution using xrandr on a privileged container to no avail.
Any help will be greatly appreciated.

You may not see anything on a connected display unless one of your containers specifically outputs something via X11 or a similar package. We have some examples here: GitHub - balena-io-examples/jetson-examples: Sample applications for the Jetson Nano, TX2, Xavier AGX and Xavier NX platforms
Do your flashed devices show up in the balenaCloud dashboard?
