I don't think that the problem is the cable or the power adapter and not the screen too. I think in that way because the same board, with the same cable, with the same power adapter, on the same TV, but with a different OS (Fedora 20) was able to show on screen KDE 4 (slow, sure, but visible). I don't know if is a software problem, and if other guys have their beaglebone black up & running with HDMI working, I have to think that is a mixed issue (hw & sw). Anyway, any advice or user experience are welcome.
