      <vdisplay>768</vdisplay>
      <vsync_start>771</vsync_start>
      <vsync_end>777</vsync_end>
      <vtotal>806</vtotal>
      <vscan>0</vscan>
      <vrefresh>60</vrefresh>
      <flags>A</flags>
      <vic>110</vic>
        </resolution>

二、 Kernel修改
    1、文件rockchip-hdmi.h
    位置：kernel\drivers\video\rockchip\hdmi\rockchip-hdmi.h
    找到以下内容：
    /* HDMI video information code according CEA-861-F */
    enum hdmi_video_information_code {
    ......
     HDMI_3840X2160P_24HZ_21_9,
     HDMI_3840X2160P_25HZ_21_9,
     HDMI_3840X2160P_30HZ_21_9, /*105*/
     HDMI_3840X2160P_50HZ_21_9,
     HDMI_3840X2160P_60HZ_21_9,
    在后面新增以下内容：
     HDMI_1366X768P_60HZ,
     HDMI_1280X800P_60HZ,
     HDMI_1024X768P_60HZ,  /*110*/

    2、文件rockchip-hdmi-lcdc.c
    位置：kernel\drivers\video\rockchip\hdmi\rockchip-hdmi-lcdc.c
    找到以下内容：
    static const struct hdmi_video_timing hdmi_mode[] = {
    ......
     {
      .mode = {
       .name = " 1024x768p@60Hz",
       .refresh = 60,
       .xres = 1024,
       .yres = 768,
       .pixclock = 65000000,
       .left_margin = 160,
       .right_margin = 24,
       .upper_margin = 29,
       .lower_margin = 3,
       .hsync_len = 136,
       .vsync_len = 6,
       .sync = 0,
       .vmode = 0,
       .flag = 0,
      },
      .vic = HDMI_VIDEO_DMT | 2,
      .vic_2nd = 0,
      .pixelrepeat = 1,
      .interface = OUT_P888,
     },
    后面新增以下内容：
     {
      .mode = {
       .name = " 1280x800p@60Hz",
       .refresh = 60,
       .xres = 1280,
       .yres = 800,
       .pixclock = 71000000,
       .left_margin = 80,
       .right_margin = 48,
       .upper_margin = 14,
       .lower_margin = 3,
       .hsync_len = 136,
       .vsync_len = 6,
       .sync = 0,
       .vmode = 0,
       .flag = 0,
      },
      .vic = HDMI_1280X800P_60HZ,
      .vic_2nd = 0,
      .pixelrepeat = 1,
      .interface = OUT_P888,
     },
