imx6x hdmi 输出1440*2560的分辨率

Question asked by sen li on Aug 26, 2018

现在需要点亮一块分辨率为1440*2560的HDMI的屏,我修改了mxc_edid.c这个文件,将mxc_cea_mode改为

const struct fb_videomode mxc_cea_mode[64] = {
[16] = {
NULL, 50, 1440, 2560, 5234, 35, 35, 12, 2, 11, 2,
FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
FB_VMODE_NONINTERLACED | FB_VMODE_ASPECT_16_9, 0,
},

};

重新编译后,启动设备。用fbset查看,分辨率确实是1440*2560,但是界面上之显示出左边一半的内容,右半边一直是黑的。请问imx6q能否支持1440*2560的HDMI屏,是否还有其他地方要修改?
