Orin Nano doesn't have 4K resolution

[Wilson_Lin]

Hi Nvidia,

I’m using Orin Nano 8GB module.
When I connect to 4K HDMI monitor.
There is no 4K resolution (3840 x 2160) in the settings of Ubuntu.
But I saw it support 4K@30 and HDMI 1.4 in the Orin Nano spec.

It’s a know issue?

Module : Orin Nano 8GB.
Carrier Board: Jetson Xavier NX Devkit
OS: L4T 35.3.1
Default DTB file.

Hi Wayne,

The device tree is wrong. Device tree shows p3768 which is orin nano devkit.
And orin nano devkit has no HDMI but only DP on it.

You need to choose p3509 board config to flash instead of p3768.

Hi Wayne,

Which config file is right in my case?
I can’t find p3509-a02+P3767-0003.conf.
Thanks reply.

p3509-a02+P3767-000x.conf.

Should be something similar to above. “x” to be any number. Just use that one.
