The HDMI monitor displays no image

What is certain is that it was working fine earlier, but this issue appeared after a while.

After the system boots up and the following log appears, the HDMI monitor remains blank for an extended period—only occasionally flickering on. What could be the problem?

Is this a custom board or NV devkit?

5

It is custom board designed based on the Jetson AGX Orin developer kit.

I simply ran the glmark2 test command for the HDMI (GPU) display; could that have caused this issue?

8

What was your software configuration to enable HDMI port there? Default mode is DP only.

9

I haven’t made any configurations to convert DP to HDMI; the display appears on the HDMI port immediately after booting up with the default SDK.

No, that is not true HDMI mode but a DP++ software support which is not stable and won’t go over 4k…
