    Hi i would like to use 2 screens at the same time with my udoo quad, how i can configure it to do that (for information i use yocto, not udoobuntu, the 2 screens works fine separately). In the documentation you said that we can use 2 screens same times in android, can we will do the same with linux ?
    i tried this :
    setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} ${hdmi_patch} fbmem=24M video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32 fbmem=24M video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32
    The screens shows the same image (or video ...) but the quality on the hdmi screen is bad (bad colors and resolution), otherwise on the lvds7 all is ok. My uEnv.txt set the screen to lvds7.

    Can you help ?
