LVDS and LCD config

Hi all,

On a custom board, we have DISP0 and LVDS0 ports that are wired.

We wish to output 720x1280 pixels on the lcd port, and 1920x1080 pixels on the lvds port.

Reading the different lvds modes, i wonder if it's possible since the formats are different. Or maybe with the dual mode ...

Is there someone which have experimented such a configuration ?

Regards,

Christophe
