    HDMI as the default or only display is not officially supported until 4AI.1.7, 4AI.1.4 did have a patch set  to make it work, but only as a development/experimental basis. You seem to be missing some patches in the upper software layers.  I recommend you move to 4AI.1.7 or 4J.2.1, use the blaze tablet board files as and example and use the correct bootargs for this particular setup by adding:

    omapfb.fb_opt=0,1920,1080 omapdss.def_disp=hdmi
