3d Frame Packing problem

    Hi,

    I'm trying to open iso full 3d but the output on HDMI is always set to custom rgb.

    Code
    tvservice -s 

state 0xa [HDMI CUSTOM RGB lim 16:9], 1920x1080 @ 23.00Hz, progressive

    I try to set on "Adjust display refresh rate" and "Sync playback to display"....nothing....

    Thanks in advance for any help
