No HDMI output displayed on monitor

[mark.satterfield]

I have an HDMI monitor connected to my own carrier board and the xrandr says:
jetson@aero-ubuntu:~$ xrandr
Screen 0: minimum 8 x 8, current 2560 x 1440, maximum 32767 x 32767
HDMI-0 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 553mm x 311mm

720x576 50.00
720x480 59.94
640x480 75.00 59.94 59.93

When I plug in and out the hdmi connection I get:
jetson@aero-ubuntu:~$ [ 42.240997] tegra-xudc 3550000.xudc: setup request failed: -22
[ 682.095882] WARNING: CPU: 0 PID: 0 at drivers/gpio/gpio-tegra186.c:937 tegra186_gpio_irq+0x1ac/0x1f0

Yet I still do not see any output on my monitor? Any ideas?
I tried to do the UseEdid false option in the xorg.conf but it prevented xrandr from working.

Hi,

You can ignore that gpio log you got. Every one has this log on their Orin when enabling HDMI.

If you are sure the Xorg log gives correct monitor info, then please attach your schematic.

There is not much software that can configure orin display setting. If we are sure all the software setting is there, then it must get changed from hardware.

We have hdmi video now, turned out to be a monitor cabling issue.
Thanks so much for all the help!
