I need to extend primary display on rk3399 so I can see big layout on the both display that are connected

Is it to modify framework native (hwcomposer, surfaceflinger etc.)

Hey @allemon,

I am also trying to get the extended display working on RK3399 board. Have you got any insight regarding this?

Thanks.
