Agx-Orin Hello, could you please help me check the issue of HDMI 4K screen not displaying?

code version :JetPack_5.1
The code modification and configuration are as follows:

It can be displayed normally without connecting to the 4K screen, but it cannot be displayed after connecting to the 4K screen。

Logs not displayed on 4k screen:
log.txt (19.7 KB)

Have you tried other cable and monitor?
