Someone have advice to let the monitor hdmi work correctly?
First of all, thanks Sebastian for your answer.
if you havn't connected or disabled keyboard/mouse the beagle will go into powersaving which also disables hdmi. try connecting the monitor and do
echo 0 > /sys/class/graphics/fb0/blank
I've tried, but no changes.
otherwise, many people have reported issues with hdmi on the beaglebone:

see also tested aka supported monitors:

I read this links, and I found interesting but 1) I don't understand the reason to ask a power supply grounded (there is no ground on board plug) and that have to be the same ground of the monitor. 2) My monitor it's a common LG 42'' inches TV. 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. Thanks in advance regards Alexjan
