Display Replication Mode support by i.MX 8X QuadXPlus

[JK_Cha]

Hi i.MX Champ !

My customer would like to implement Dual display as replication mode with MIPI-DSI and LVDS of i.MX 8X QuadXPlus.

They have tried to make dual display system using external MIPI to LVDS bridge IC. 

They are developing both MIPI and LVDS to output the same camera image.
I'm looking for a way to make both displays work in replication mode, can you guide me?

According to LINUX USER GUIDE below, I can not figure out if i.Mx 8X would support the routing a same video source to multiple display mentioned in 7.3.1.6.2 even without sink feature.

Please provide us with detailed guidance to enable routing a same video source to dual display via MIPI-DSI and LVDS outpus.

Thanks.

Regards, 

James

for multi display support on imx8qxp, requires the mouse navegation on these displays in order to enable it.

Let me modify Display type from MIPI-DSI to LVDS. 

They're going to use LVDS0 and LVDS1 in replication mode. 

Is there anyway to enable it without the mouse navigation handling? 

Customer wants to activate the auto start displaying with both LVDS0 and LVDS1.
