大家好:

       现在在调试一款HDMI的屏,分辨率是1440*2560的。

我用的Linux版本是imx6q 3.10.17

我修改了mxc_edid.c中const struct fb_videomode mxc_cea_mode[64]的设置,将里面的参数改为

[1] = {
NULL, 30, 1440, 2560, 6734, 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,
},

但是编译重新烧录后,界面有显示但是只能显示一半,显示效果如图

请问有没有办法解决?

另外imx6q能否支持1440*2560的分辨率?
