The issue is your display is not providing the edid when queried and in standby (usually they do - which is much more convenient).
You can capture this edid to a file, and use that.copy the two edid files to /lib/firmware/edid1 and /lib/firmware/edid2.
Now add to cmdline.txt:and reboot.

Code:
# find /sys -name edid/sys/devices/platform/axi/axi:gpu/drm/card1/card1-HDMI-A-1/edid/sys/devices/platform/axi/axi:gpu/drm/card1/card1-HDMI-A-2/edid
Now add to cmdline.txt:
Code:
drm.edid_firmware=HDMI-A-1:edid1 drm.edid_firmware=HDMI-A-2:edid2
