现在需要要输出为1920*1200P60的显示输出，在哪个地方可以调节呢。给个思路，在源码的哪个地方可以调节这个参数。理论4K都能显示，向下应该是没有问题的

我刚找到了一个朋友与我有相同的需求，只是他的需求是1366*768
http://developer.t-firefly.com/f ... =%B7%D6%B1%E6%C2%CA

他解决的办法是添加一个配置信息：
我已经解决了这个问题，在lcd-box.dtsi里面添加，       timing1: timing1 {
                              screen-type = <SCREEN_LVDS>;
                              lvds-format = <LVDS_8BIT_2>;
                              out-face = <OUT_D888_P666>;
                              clock-frequency = <85500000>;
                              hactive = <1366>;
                              vactive = <768>;
                              hback-porch = <213>;
                              hfront-porch = <70>;
                              vback-porch = <24>;
                              vfront-porch = <3>;
                              hsync-len = <143>;
                              vsync-len = <3>;
                              hsync-active = <1>;
                              vsync-active = <1>;
                              de-active = <1>;
                              pixelclk-active = <0>;
                              swap-rb = <0>;
                              swap-rg = <0>;
                              swap-gb = <0>;
                           };

问题是我如果添加1920*1200P60需要怎么给参数呢？

我也找到本机的配置信息，如下，

我是不是应该加这个参数：
timing3: timing3 {
                              screen-type = <SCREEN_RGB>;
                              out-face = <OUT_P888>;
                              clock-frequency = <？？？？？？>;
                              hactive = <1920>;
                              vactive = <1200>;
                              hback-porch = <???>;
                              hfront-porch = <??>;
                              vback-porch = <??>;
                              vfront-porch = <?>;
                              hsync-len = <??>;
                              vsync-len = <?>;
                              hsync-active = <?>;
                              vsync-active = <?>;
                              de-active = <0>;
                              pixelclk-active = <0>;
                              swap-rb = <0>;
                              swap-rg = <0>;
                              swap-gb = <0>;
                     };

这些参数有什么定义规则？或帮我填一下，谢谢

是4.4.2版本，输出显示为HDMI。

以上红色是我加的与修改的地方。
但编译完烧写进去，还是没有1920*1200P60显示项
1、请问这个修改项对吗
2、还要不要改别的地方的配置

请指教

HDMI配置修改

作者: isle 时间: 2015-8-27 15:12
你是说设置里面的HDMI 选项？那个你看下kernel里面的rk_hdmi_lcdc.c 以及上层Setting里面hdmi mode部分。
修改dts里面，只是默认直，并不增加HDMI输出选项

先把驱动调成功再调上层吧，上层要学过APP的才好改，如果不会添加的，就把一项的字符串给改了。驱动相应的改
