Greetings @kannika.k,

On my setup TorizonCore with HDMI works fine by default. What Carrier board and version are you using? Also what version of the DSI/HDMI adapter are you using?

Finally did the HDMI display work for you when using Easy Installer? Or did it also not work there?

Best Regards,

Hello @jeremias.tx
Thanks for your reply.
I change TorizonCore from the 5.5.0 version to version 4.0.0 and everthing works now.
Carrier board version → v1.0
DSI/HDMI adapter → v1.0
DSI/HDMI display work when using Easy install.

Is HDMI native can work with TorizonCore ?

This here seems to be your issue. There was a major update to most Verdin family hardware between V1.0 and V1.1. More details on this page: Verdin Product Family Specification Update | Toradex Developer Center

While you do have the 2nd generation V1.1 module you still have the 1st generation V1.0 carrier board and DSI/HDMI adapter. Unfortunately this means full software support is only possible on older software (pre 5.1.0 as per the page I linked). While it is possible to run the 5.5.0 software with the out-dated hardware, not everything will quite work as expected. Like HDMI for example.

This explains, why I had a different outcome than you since I have updated V1.1 hardware for everything. I would highly recommend getting updated hardware for the carrier board and DSI/HDMI adapter if possible. Otherwise you’ll be stuck to using older software.

Best Regards,
