Hi team,
i read some queries in the forum regarding the concerns in implementing of DP and HDMI.
Could you clarify the below queries?

Are there any issues in implementing 2x DP and 2x HDMI ports in custom carrier board for jetson Thor T5000?

Also, Can we implement DP alt mode over type C and expect it to be working after the software issue is fixed?

Can all 4 outputs stream different outputs simultaneously? Is it validated?

If 2 outputs are connected altogether which output lane will be of priority?

Thanks.

  1. 4 display cases have some issues which could not work all 4 at same time. We are still working on a fix.

  2. What does that mean DP alt mode over HDMI?

  3. If 2 outputs are connected together, the one that configured as display0 in the DCB image would be with higher priority.

2.) Sorry my mistake. Its DP alt mode over type C.
Would it work anytime soon if the hardware is implemented in the custom carrier board?

Need to clarify something here

DP-Alt mode is already enabled on Jetpack7.2. However, you have to make sure your USB design could work and let HPD signal got toggled when monitor type C cable connected.

Hi wayneWWW,
Thanks for clarifying. Does it work in the current jetson thor Developer kit with the latest jetpack 7.2?

Thor devkit does not work because the USB PD firmware on it is not supported yet.

It does not mean DP ALT is not working on a custom board. If your custom board has right design, then it would work .

Thanks for the information

So, for hardware implementation, I hope i can route whichever video output lanes i want and terminate it to DP , HDMI, Type C connector and configure it in the software for prioritizing right?

yes, correct.
