i.MX8M Plus – HummingBoard 8P Edge AI HDMI cable connected to monitor no signal

I bought i.MX8M Plus – HummingBoard 8P Edge AI recently. I powered it up and see the green lights on the board. But the hdmi cable connected to the monitor does not receive any signal. I use the same hdmi cable and the monitor to work with NVIDIA Jetson platform, there is no issues.
Is there any known issue wih the hdmi? Also what type of hdmi cable should I use?


You should just be using a standard hdmi to hdmi connector. The HDMI output will only work under Linux, not under u-boot.

Please attach the output of dmesg so I can review the boot logs.
