I meant was the voltage related to hdmi and its components are matching as mentioned in the documentation, so there’s no hardware issue.
I found a source for headless display and tried that, it worked fine via VNC server.
My doubt was does the VNC needs HDMI/display drivers for it to display over wifi using VNC or is it not related to it.
Just to clarify. I can guarantee that VNC has nothing to do with your issue for now.
If you want to discuss about it, you could file another topic and we can discuss that for what you need.
For current issue, you could try to check /sys/kernel/debug/gpio and see if the GPIO pin for hpd you are using got toggled when you hotplug the cable.
If you don’t know what I am talking about, find someone who is familiar with linux kernel on your side to help you.
In /sys/kernel/debug/gpio the hdmi2/0_hpd is in hi IRQ
and in the dmesg i got:
[ 1.129797] tegradc tegradc.0: probed
[ 1.130520] Console: switching to colour frame buffer device 80x30
[ 1.130572] tegradc tegradc.0: fb registered
[ 1.132104] tegradc tegradc.1: disp1 connected to head1->/host1x/sor
[ 1.132218] tegradc tegradc.1: No lt-data, using default setting
[ 1.132260] tegradc tegradc.1: No hpd-gpio in DT
You could ignored above. Just a dummy log.
In /sys/kernel/debug/gpio the hdmi2/0_hpd is in hi IRQ
Does the state change when you hotplug in/out the cable?
No, the state is 0 itself.
But got different in dmesg:

Do you really have some software guys on you side that can come to reply this post?
I feel you don’t have the ability to handle the discussion here. Sorry to say that.
There are lots of conflicts in your comment that we are not possible to fix anything based on this.
I asked whether your HDMI cable plug in/out trigger anything in the dmesg for HDMI driver. Previous log and discussion indicate there is not.
Now you share a log that when you plug the HDMI cable, lots of things from DP driver comes out.
If (2) is true, it also indicates your hardware design does not match to NV devkit. It means your previous comment for your carrier board is also wrong.
You could try to disable tegradc 1 in the device tree first in case this thing is causing noise to your log. But of course this test is only based on your hardware is really same as what you described.
The 2nd point was just that one time.
Again when we tried it the output was same as before.
No change in gpio is observed when tried again.
Then it is going back to this comment again.
