Guys, I don't know how to thank you! It seems to be working beautifully!
To Tell the truth, I don't know any differences in gbm, it works really well!!

 Could you describe the problem again that you had before that GBM fixed?  

The problem was, if I was passing hdmi1 to hdmi2 and I went back to hdmi1, I lost the signal.

My Nuc (NUC7PJYH) has two Hdmi - only the first (HDMI-A1) is connected to Denon.
In Denon -> hdmi1 = Kodi, hdmi2 = sky;
if I wanted to watch Sky and later watch a movie with Kodi, I lost the video signal, and the only solution was to make a reboot
