大家有遇到过这种情况吗？点的是双8lvds屏，看颜色应该是正常的，但是有一层灰，正常的颜色见图片

麻烦有遇到的朋友指点一下

[whycan]

lcd_lvds_colordepth = <0>;

会不会是这个问题呢？

@whycan
这两个测试过了，有反应，但是，还是会有这个暗
lcd_lvds_colordepth = <0>;
lcd_lvds_mode = <1>;

把缓冲区的数据dump出来，用电脑软件看下，颜色是否正常。

@whycan
您好，这个应该如何操作

@zhoutian

cat /dev/fb0 > /mnt/SDCARD/fb0.rgb

用这个软件看:
