请问RK3399如何控制通过TypeC-DP输出视频，相关驱动代码在什么位置，分辨率等显示参数在哪里设定，是否有相关的开发文档？
官方好像說 TypeC-DP输出 原生就支持了.可是我用 Type-c 轉 DP+USB 3.0 試不出來.看串口是有些相關訊息出現的.

这种情况下USB 3.0可以用吗？

Type-C 插上去有以下訊息, USB3.0 插上去無反應：（Type-C hub 是調在 4-lane DP)

接了兩個視頻輸出 一個 HDMI 1080P, 一個 Type-C DP 接 4k 屏, Display Output 兩個都只能最高分辨率 1920*1080 60Hz.
選了 display different content on double display, 還是只能顯示相同內容.
你在哪里配置的display different content on double display？
这里有一篇RK3399双屏异显的文章，你可以参考一下

那是 eDP+MIPI 的雙屏雙顯, 有沒 HDMI+ Type-C DP 的雙屏雙顯？

&hdmi_rk_fb {
rockchip,hdmi_video_source = <DISPLAY_SOURCE_LCDC1>;
};
&cdn_dp_fb {
dp_vop_sel = <DISPLAY_SOURCE_LCDC1>;
};
如果HDMI和DP使用的是相同的显示数据源；
把rockchip,hdmi_video_source和dp_vop_sel 选择为不同的显示数据源。
&hdmi_rk_fb {
rockchip,hdmi_video_source = <DISPLAY_SOURCE_LCDC0>;
};
&cdn_dp_fb {
dp_vop_sel = <DISPLAY_SOURCE_LCDC1>;
};
如果HDMI和DP使用不同同的显示数据源，还是显示一样的话，那就看下LCDC0和LCDC1是不是没有真正的创建为异显的显示源。
