android4.0 A10开发板，如何实现分屏（多屏幕显示）不同的内容
============问题描述============
设想是如上图所示
目前的情况是，我有A10的开发板，android4.0.4
如果有同行的话，希望能指点一下
目前能单独显示vga,hdmi,lvds三种屏幕
vga 和 hdmi如果同时插入的话总有一个是不能正常显示的，因为我配置的
sys_config1.fex文件里面有单独针对的参数，
只要能让我实现分屏显示不同的内容（不同的屏，显示的不同的内容连接的是同一块板子）就行，连接显示是vga和tv vga和hdmi hdmi和tv三种哪个都行
我手边有开发板，有源码，不知道哪位知道如何解决！
