1、修改文件，打开调试模式，得到 EDID 信息后，记得关闭

Detailed Timings 是主要的 LCD 参数，Supported VESA Modes 是 LCD 支持的分辨率。
通过源码查看各参数的含义：
路径：kernel/drivers/video/fbmon.c
DPRINTK(" %d MHz ", PIXEL_CLOCK/1000000);
DPRINTK("%d %d %d %d ", H_ACTIVE, H_ACTIVE + H_SYNC_OFFSET, H_ACTIVE + H_SYNC_OFFSET + H_SYNC_WIDTH, H_ACTIVE + H_BLANKING);
DPRINTK("%d %d %d %d ", V_ACTIVE, V_ACTIVE + V_SYNC_OFFSET, V_ACTIVE + V_SYNC_OFFSET + V_SYNC_WIDTH, V_ACTIVE + V_BLANKING);
DPRINTK("%sHSync %sVSync\n\n", (HSYNC_POSITIVE) ? "+" : "-", (VSYNC_POSITIVE) ? "+" : "-");
dts
由此可以得到 LCD 的各参数：

PorI：0 为不是隔行扫描。定义文件路径：/kernel/include/uapi/linux/fb.h

5、此时 HDMI 可以正常输入 1024x600 的分辨率，但是实际显示可能有问题。
根据显示器的 EDID 修改 dts 中加载的屏参文件，修改值与添加到 HDMI 数组中的相同。

6、编译烧录，HDMI 显示正常，确认当前分辨率可以在设置 -> HDMI ->分辨率设置中查看，也可以通过指令查看。
$ cat /sys/class/display/HDMI/mode
在dts中写分辨率 发现 图标变了。。
问题
现在 lvds 和 hdmi 共用 参数 （不对）——

android5.1设置默认开机横屏
2017年3月16日 16:40 阅读 3016 新浪博客
1、进入framework/base/core/res/res/values/config.xml
修改config_lidOpenRotation = 0 ;----> config_lidOpenRotation = 90 ;
2、进入framework/base/services/core/java/com/android/server/wm/WindowMangerService.java
修改int mRotation = 0 ;-----> int mRotation = 1 ;
3、进入framework/base/services/surfaceflinger/DisplayDevice.cpp
修改setProjection(Displaystate::eOrientationDefault, mViewprot ,mFrame )------>
setProjection( Displaystate::eOrientation90 ,mViewprot , mFrame )
编译成功刷入系统会出现开机动画部分只显示3/4解决方案如下：
1、进入framework/base/cmds/bootanimation/BootAnimation.cpp
修改status_t BootAnimation::readyToRun函数中的
spcontrol=session()- >createsurface(String8(“BootAnimation”),dinfo.w,dinfo.h.PIXEL_FORMAT_RGB_565);
为：
spcontrol=session()- >createsurface(String8"BootAnimation"),dinfo.h,dinfo.w.PIXEL_FORMAT_RGB_565);
2、进入/framework/native/services/surfaceflinger/DisplayDevice.cpp
修改函数 void DisplayDevice::setProjection(intorientation, conts Rect&newViewport,constRect&newFrame)中
if(!frame.isValid()){
frame = Rect(w,h);----->frame = Rect(h,w);
}
在Transform R; 下面添加
orientation = DisplayState::eorientation90;
3、进入/framework/native/services/surfaceflinger/surfaceFlinger.cpp
修改函数voidSurfaceFlinger::onInitializeDisplay()中：
d.orientation = DisplayState::eOrientationDefault ;----->d.orientation=DisplayState::eOrientatio90;
最后编译生成镜像，问题解决。
// 只能保证横屏 转成竖屏出问题（有一半黑）logo 没变过来。

有一例子
814.192892] Detailed Timings
[ 814.192928] 148 MHz 1920 2008 2052 2200 1080 1084 1089 1125 +HSync +VSync
```go
timing0: timing0 {
clock-frequency = <148000000>
hactive = <1920>;
vactive = <1080>;
hback-porch = <188>;
hfront-porch = <148>;
vback-porch = <4>;
vfront-porch = <36>;
hsync-len = <144>;
vsync-len = <5>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;//1
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
问题分析
1.dts 中
&disp_timings {
native-mode = <&timing0>;
};
&rk_screen {
display-timings = <&disp_timings>;
};
起了什么作用？？？
