# rk3288 android7副屏旋转显示异常与满屏修改 #

主屏使用的是HDMI，副屏使用的lvds  
主屏是HMDI转lvds 由于转接模块不支持1280x800 所以设置了hdmi输入源为1280x720 为了保证主屏正常显示 修改了framebuffer为1280x800  
就是由于修改了framebuffer导致副屏显示旋转异常,一定不要设置persist.sys.framebuffer.main这个参数

persist.sys.framebuffer.main=1280x800

查找rk资料了解到，双屏同显时，副屏显示是在主屏显示的基础上进行的缩放，双屏异显时，副屏显示是按照副屏实际物理分辨率重新进行了UI绘制  
下面的patch能解决副屏旋转后显示异常及同显时不满屏的问题  
修改patch如下
