I bought the Waveshare 3.2-inch HDMI LCD screen and plugged it into the Nvidia Xavier NX with the latest Jetpack 5.1x.
But after powering up, the screen just shows Nvidia icon for some seconds during booting up.
Then the Waveshare screen is blank: there is nothing on the screen.
The video of the blank screen after powering up:

I checked kernel dmesg, and it shows as follows:

On the Waveshare website, it is said that the 3.2-inch HDMI LCD screen works on the Nvidia.
Can you please advise me on how the Waveshare screen could work on Nvidia?
Thanks a lot in advance.
