Jetson Linux running on NX from R35.5.0 to 35.6.2 has no display output or graphical interface. What I can confirm is that my cable connections are fine, and apart from the lack of display output, Jetson Linux functions normally. Also, R35.4.1 and earlier versions can display output.
Hello @xl370
Are you using a devkit or a custom board?
You can check the post at Display Issue after Updating to L4T 35.6.0
You can check the patch and information related to the monitor at Jetson Xavier platform specific configurations — NVIDIA Jetson Linux Developer Guide 1 documentation and Jetson Xavier platform specific configurations — NVIDIA Jetson Linux Developer Guide 1 documentation
Furthermore, you can test by hotplugging the monitor after the system is up to check if the display works or not.
I hope this helps!

Hi ! EduardoSalazar96.
I customized the circuit board, but the HDMI circuitry is the same as the official board.
It’s working now. However, you have to hot-plug it to make it display.What is the reason for this?
Hi !
This is a weird problem. After I refresh NX again, the monitor stops working. Hot-plugging the cable doesn’t help either, but switching to R35.4.1 or earlier versions doesn’t have this issue.
Hello @xl370
This Display Issue after Updating to L4T 35.6.0 - #13 by joseph.zc post seems to have a solution. Did you try it?
Also, did you check the other links that I mentioned in my previous answer?
Best regards!
Hi !
I solved the problem.
I modified the ‘hardware/nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-p3509-disp.dtsi’ file.
&head0 : nvidia,dc-connector = <&sor0>; -- > nvidia,dc-connector = <&sor1>;
&head1 : nvidia,dc-connector = <&sor1>; -- > nvidia,dc-connector = <&sor0>;
Then recompile the kernel and flush the kernel to the NX.
