     can you help me?

     i would like to having a display on the HDMI and LVDS.So,i refer to the sarbresd linux release note.I modified the kernel boot parameters as follows:


    set bootargs console=ttymxc0,115200  init=/init  video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:dev=ldb LDB-XGA if=RGB666 fbmem=30M,vmalloc=400M androidboot.console=ttymxc0


    At last ,i found always to be display either hdmi or LVDS. In a word ,one of these can be displayed.


    can you told me the answer?
