各位好！
我在rk3128 android5.1上去点一个 10.1寸的1024x600的lvds屏；现在屏点亮了，但显示效果有问题；
在uboot中，看显示效果应该是正常的；
进入android显示异常，出现上下两个android 界面，但是插入Hdmi线接到显示器，则两个显示正常。请问这个是什么原因？
dts文件及屏参文件修改如下：
&fb {
// rockchip,disp-mode = <NO_DUAL>;
// rockchip,disp-policy = <DISPLAY_POLICY_BOX>;
rockchip,disp-mode = <ONE_DUAL>;
rockchip,uboot-logo-on = <1>;
};
&disp_timings {
native-mode = <&timing0>;
};
&rk_screen {
display-timings = <&disp_timings>;
};
&lvds {
status = “okay”;
pinctrl-names = "lcdc";
pinctrl-0 = <&lcdc0_lcdc_d>;
};
&lcdc {
status = “okay”;
rockchip,fb-win-map = <FB0_WIN0_FB1_WIN1_FB2_WIN2>;
};
屏文件：
disp_timings: display-timings {
native-mode = <&timing0>;
timing0: timing0 {
screen-type = <SCREEN_LVDS>;
lvds-format = <LVDS_8BIT_1>;
out-face = <OUT_P888>;
color-mode = <COLOR_RGB>;
clock-frequency = <60000000>;
hactive = <1024>;
vactive = <600>;
hback-porch = <90>;
hfront-porch = <160>;
vback-porch = <13>;
vfront-porch = <12>;
hsync-len = <70>;
vsync-len = <10>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
};
异常显示：
Hdmi接入显示屏，则显示正常：
谢谢各位！
