Hi Markus,
I was hoping to see some answers to your question. I have tried something similar and ended up with a defunct HDMI. In retrospect I suspect the problem was related to the common earth and I asked the local repair shop proprietor who specializes in higher end video cameras for an opinion. His comment surprised me – he thought I was unlucky and that the HDMI failure was unrelated. As I feel that I might not have made myself clear I would like to hear other opinions.
What I was trying was a little more complicated than your proposal. I was using a DP6 monitor that has a generous voltage range of 6-18 volts and a Panasonic XC-X900 that requires an external supply of 9.4 volts. To power the camera I had two 7.2volt NP-F970 batteries in series giving ~ 14.4 volts that I regulated to the required 9.4 volts with an LM 318T regulator circuit. To power the monitor I could select one or other of the batteries meaning that earth could be at the same potential as that for the camera or higher depending which battery I had selected. My loss of HDMI out on the camera did not happen instantly, I had some use from the set-up. I have replaced the camera but I am not keen to repeat the experiment without further advice.
