How to test DP MST mode output?

How to test DP MST mode output?

test path
A → B → C

A : ORIN EVK
B: DisplayPort MST Hub

C: DP 4K Display

Is this test path correct?
JetPack 5.0.1 change how to set the implementation?

This looks correct.

Is there any modification required for JetPack 5.0.1??

You can also test with the DP monitor which claims they supported MST.

No, I don’t think any modification is needed. We have other customers trying that before. Pure sdkmanager shall work.

But since this is still preview version release, not sure if you would hit bug after some operations (blank/unblank).

but DP HUB + monitor ASUS PA238 connect to PC is ok …

Hi,

Per checked, our QA team is using Daisy chain with monitor supported MST.

I used Dell display that supports Daisy Chaining MST.

No screen that supports DP MST so can’t test …

Use DP HUB but no response and cannot display
see /var/log/Xorg.0.log no any message

Any suggestions on how to debug the DP MST process??

Can you tell me the model of the test screen?

Can you tell me the model of the test screen?
It feels like there is a compatibility issue with DP MST…
