Is the Agx-Orin supporting hdmi 4k resolution?

The xrandr show the system only support full hd resolution

Yes it supports 4k.
Please also try other monitors too.

BTW, why are you still using DP and you ask me about HDMI?

We tried two of different brand HDMI monitors, both provided the same information. I’m wondering also is it a bug for that DP-1 named?

Is this your custom carrier board? If so, how did you bring up your HDMI interface?

Yes, it is our custom board, we do not changed any thing about display. We flashed this image to boot up system on Dev-Kit with a DP display prior and flashing this image to our custom carrier board with HDMI output without modified any display configuration.

Then it is wrong… it is not a HDMI interface… it is still DP…

Is the file “tegra234-dcb-p3701-0000-a02-p3737-0000-a01.dtsi” for DP output?

You need to generate new dcb file for HDMI. The default on in source code is for DP only.

Also… suggest you to file ticket for this issue. I am not sure why you are asking this on forum.

Also, we think this will need our hardware engineer to review your schematics.
