Opengl how to output two displays on jetston tx1

The requirement is to output one STD PAL (720x576)display and another VGA ()display.

How can we customize the tx1 to output opengl windows onto two display devices?
case 1. if the contents of the two displays are synchronized, only resolutions are different;
case 2. the contents of two displays are also different.

Hi HooverLv,

Which interface do you want to use for that STD pal? We have few thread discussing about dual-monitor.
