Issue with Display Output on Jetson Nano Orin

I am experiencing an issue with my Jetson Nano Orin device. While turning on the device, I am receiving an error message on the display:
“The current input timing is not supported by the monitor display. Please change your input timing to 1920x1080 ,60Hz or any other monitor listed timing as per the monitor specifications.”
This issue was not present until yesterday, as the display was working fine without any such error. Now, I am unable to get the graphical user interface (GUI) to appear, and the device seems to be stuck on this error. I have tried connecting with another monitor, but the issue persists. Image attached for reference.

Is this a pure DP monitor or going through an adapter?

Hi Wayne, It is pure DP monitor.

Is this on NV devkit or a custom carrier board?

I am using this device NVIDIA® Jetson Orin™ NX 16GB AI Device - reComputer J4012

Specification of the device - Powerful and compact edge AI device with NVIDIA® Jetson Orin™ NX SoM, pre-built Jetpack 5.1.1, 128GB SSD, 4x USB 3.2, HDMI, GbE, carrier board also includes M.2 key E for WIFI, M.2 Key M for SSD, RTC, CAN, 40-pin and more.

This is not NV devkit. You should ask vendor how to flash their board.

For example, default BSP from NV devkit does not support HDMI at all.

Understood, thanks for your prompt responses!

how come it worked earlier and suddenly stopped working?
even though default BSP from NV devkit does not support HDMI at all.

There were few updates I updated and once I was done with those updates I started facing this issue after restarting the jetson device.
