Hi,

I would like to output from the Jetson Nano devkit HDMI to 1920x480 monitor.
This monitor was displayed correctly with PC (Windos10).
However, with Devkit, both HDMI and Display port will either not display at all or will very noisy screen.
I believe that Devkit is not capable of displaying images on monitors with special resolutions.
Can you tell me how to set up the Jetson Nano to display images on such a monitor?

Best Regards,

It may be hardware limitation that such special mode is not supported.

You mentioned that it is a hardware limitation. Does this mean that it is a specification of NANO Module? Can I fix it by modifying the carrier board?

This may not be a problem that could be created by making a carrier board… Just jetson nano may not support it.

Which one do you see blanked screen? HDMI or DP?

Both HDMI and DP be blanked screens.

Can you connect it to the HDMI and share me the result with below command?

  1. dmesg

  2. xrandr (export DISPLAY=:0 before running xrandr)

Please see the attached files for the dmesg and xrandr logs.

xrandr.txt (336 Bytes)

Hi,

The log looks like a disaster. Have kernel panic and the edid seems not match to the mode you get there.

Can you dump the log with just hotplug case? I mean you boot up the board without connecting the monitor. After system is ready, plug the HDMI cable and then dump the dmesg/xrandr again.

Hi,

I have attached the logs with the hot plug case.
dmesg_2nd.txt (78.8 KB)
xrandr_2nd.txt (335 Bytes)

Could you provide a list of monitor resolutions supported by NANO module?

Every CEA mode from HDMI2.0a/b should be supported.
