Trying to get two extended displays on an Orin Nano (JetPack 6, r36.5). Found thread 341579 where @hokfung.lee had it working on r36.4.4 (xrandr showed DP-0.3 + DP-0.4 extended), but the hub model was never posted and the thread’s closed now.
My DP-to-2xHDMI hub (StarTech MST14DP122HD) gets nothing, 0 outputs in xrandr, no HPD or EDID at all.
@hokfung.lee which hub did you use, and was it DP-to-2xDP or DP-to-2xHDMI? Any device-tree or xorg tweaks?
And for NVIDIA: is there a specific MST hub model that’s confirmed working on Orin Nano? Thanks.

I could not find clear support for that in the provided Jetson Orin Nano documentation. The context does not specify a particular MST hub model that is confirmed to work on Orin Nano for dual extended displays with JetPack 6.
However, it is mentioned that a user had it working on r36.4.4, but the hub model was not posted, and the thread is closed. The provided context does not include information about specific MST hub models or device-tree and xorg tweaks for this setup.
For more information, you may want to check the NVIDIA forums or contact NVIDIA support directly, as they may have more detailed information or specific recommendations for MST hubs compatible with the Jetson Orin Nano.

There is no MST hub verified by NVIDIA in the Jetson AGX Orin Series Supported Component List but the user in this comment successfully used a solution from Synpatics: Support on mst board - #6 by jameskuo
Beware the information in that post and the linked one about disabling DSC in the driver.
NVIDIA’s testing used MST daisy-chained through monitors.
