DisplayPort Output Issue on NVIDIA Jetson Orin Nano after Resolution Change

Hello,

I am currently working with the NVIDIA Jetson Orin Nano board. I’ve encountered an issue where, after the NVIDIA logo appears during boot, the login screen does not appear and it states that there is no DisplayPort (DP) output.

Interestingly, when I remotely connect via PuTTY, it appears as though the boot process has completed normally. This has left me puzzled as to why there is no DP output.

I should note that the board was previously working fine at a resolution of 1280x720p. The issue seemed to have started after I changed the resolution.

Any insights or suggestions on why this might be happening and how to resolve it would be greatly appreciated.

Thank you in advance for your help.

Better telling which jetpack version is in use and what carrier board is in use.

What is the result of xrandr and /var/log/Xorg.0.log and are you still be able to change mode by using xrandr.
