HDMI not working

Hardware:
Orin nano module P3767-0003 + customboard.

Custom borad status:
Modified form Orin nano dev kit, but changed DP to HDMI.

Jetpack:
5.1.3

Problems:
Tested two monitors, HP and Waveshare. On the HP monitor everything works fine. But on the Waveshare monitor there is no output. I also tested another monitor and it also didn’t work properly.
Waveshare monitor works fine on other devices.

When unplugging and plugging the monitor, the Xorg.0.log is as follows:
Xorg.0.log.txt (3.1 KB)

The EDID of both displays can be read normally:
xrandr --props -display :0.0 | edid-decode
edid_hp.txt (4.8 KB)
edid_waveshare.txt (4.5 KB)

Thanks!

I don’t see any specific error from your xorg log.

Will it work if you switch to 1920x1080 on waveshare by using xrandr command?

Do you mean this?
xrandr --fb 1920x1080 -display :0.0
Still can’t output normally.

How to determine whether Orin nano is in DP++ mode or HDMI mode？

first, give us your xrandr result.

I changed the resolution according to here, but it still doesn’t display properly.
xrandr result for waveshare monitor:

$ xrandr

If you saw “HDMI-0” in xrandr then it is not in DP++ mode anymore.

So even using “xrandr --output HDMI-0 --mode 1920x1080” won’t give you the GUI?

Sadly yes.
