Running 5.5-inch 4K display on Jetson Nano

Hi,

Does anyone have an idea how to run the 5.5-inch 4K displays shown in the link below on the Jetson Nano board?

Once I connect the driver board to the HDMI port of Jetson nano it does not show anything. Is there any specific driver that must be installed on Linux on Jetson nano in order to make this display running?

Thanks in advance for your kind replies.

Bests,
Darelli

If the board is HDMI compliant, then it should “just work ™”

Does the display work with other computers? Does it have proper power?
What does the Xorg.log and dmsg and console UART logs say when the Jetson starts up?

Thanks @snarky for your reply.

The output dmesg and Xorg.log are as follows:

dmesg :
