These DTS files affect the behavior of the displays connected to the mini-SAS connectors, which expand your
multimedia experience in combination with the range of daughter cards available for the i.MX8QXP MEK.

How to set you can see

Hi Rita Wang,

Thanks for your feedback. 

Sorry, maybe I'm not statement my question clearly. Now we have success drive two display (one is via DSI0 and another is via DSI1)  on imx8qxp board. my question is:

In user space, how the application switch the content to different display panel?  For example, we call DSI0 lvds as display0 and DSI1 lvds as display1, in user space application, how to decide the application's contest displayed on display0 or display1? 

thanks.
