Hi,

Does PSDK on Jacinto7 support display port's MST functionality ?

Hi Victor,

This is not yet supported and as of now, no plan to support it.

Why do you require MST functionality? to connect multiple displays?

Hi Brijesh,

Thanks for the quick answer ! Yes it would be to connect 3 displays. What alternatives do you suggest ?

regards,

Victor

Hi Victor,

I think you could use DSI, eDP and HDMI outputs to have three displays. There is a SRV+AVP demo in vision apps, which uses two displays, eDP and HDMI. we can add DSI to it for the third display.

But please note that input pipelines are 4 only. So only one of these three display can have 2 pipelines.. Rest two will have to use single pipeline.
