Hello to everyone browsing this post,
Regarding the use of the AGX Thor device, I have encountered an abnormal phenomenon.

After powering on the AGX Thor device and connecting a 4K monitor via the DP interface with a cable, the display shows abnormalities, with pixel dynamic disorder. Only rebooting the device, restarting the device, or performing a system soft reboot (Ctrl+Alt+Print Screen+r+e) can restore normal display.
The Jetpack version installed on the Thor device is as follows:

root@zzy:/home/zzy# cat /etc/nv_tegra_release

R38 (release), REVISION: 2.2, GCID: 42205042, BOARD: generic, EABI: aarch64, DATE: Thu Sep 25 22:47:11 UTC 2025# KERNEL_VARIANT:

ootTARGET_USERSPACE_LIB_DIR=nvidiaTARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidiaINSTALL_TYPE=

How should this issue be resolved?

Is this on NV devkit or custom board?

Did you observe issue on other DP monitors too?

The problem occurs when using the NV devkit device. I haven’t tried it on other monitors,but I can assure you that my monitor works fine when connected to a Windows host.
