Orin NX can not display 1080p on HDMI with monitor - ASUS VS247H

I used Orin Nx and monitor, ASUS VS247H, and just only display less than 1600 x 900 resolution.

How could I do to display 1920x1080 resolution ?

How did you flash your board?

I used orin nx SOM + xavier nx ca board.

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal

Could you share the result of xrandr command?

Could you share the log (/var/log/Xorg.0log)? There is no 1080p list out in the xrandr.

Xorg.0.log (17.5 KB)

The result looks weird.

Is it a custom board or nv devkit?

Please enable full log in xorg by below method and share log again.

#Add below option in /etc/X11/xorg.conf, ‘Section “Device”’. Verbose mode logging will be shown in

Section “Device”

Option “ModeDebug”


The log is produced by custom board,
but I had the same problem with nv devkit (Xavier NX ca board)

Xorg.0.log (64 KB)


The log says it fails to read EDID from the monitor.

[ 16.500] (WW) NVIDIA(GPU-0): The EDID read for display device HDMI-0 is invalid:
[ 16.500] (WW) NVIDIA(GPU-0): - The EDID has an unrecognized version.

I don’t think devkit software/hardware has such issue. Could you test more monitors on devkit and check the xorg log with above method?

Incidentally, if the carrier board is from a third party, then typically device tree edits are required for i2c to function correctly. The DDC wire of HDMI uses i2c protocol, and is what reads EDID. Without that there is no possibility of automatic setup, and only defaults would be visible. With the failed EDID I am surprised the Xorg log showed any mode pool at all (which is normally the result of EDID).
