RK3288 android5.1 1920*1080分辨率无法全屏显示，显示器设置也无法全屏，
右边和底部无法填充满，鼠标也不能划过去。
设置1280*720之后 显示器设置全屏显示 可以全屏
lcd-box.dtsi中
timing1: timing1 {
screen-type = <SCREEN_RGB>;
out-face = <OUT_P888>;
color-mode = <COLOR_YCBCR>;
clock-frequency = <148500000>;
hactive = <1920>;
vactive = <1080>;
hback-porch = <148>;
hfront-porch = <88>;
vback-porch = <36>;
vfront-porch = <4>;
hsync-len = <44>;
vsync-len = <5>;
hsync-active = <1>;
vsync-active = <1>;
de-active = <0>;
pixelclk-active = <0>;
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
有1920设置。
请问各位大神该如何解决
