Problems with several new HP EliteDisplay E221i's, lose signal

Product Name: HP EliteDisplay E221i
Operating System: Microsoft Windows 7 (32-bit)

Hello. My company purchased over 100 of these monitors, and with a very small sample (about 5 so far), we're experiencing an issue where the monitor loses the input signal and goes dark. We've done troubleshooting to include the basics (check connections, reseat connections, turn off/on, factory reset) to more severe 'fixes' (change video cables, video cards, update display drivers, update computer BIOS, install HP's dedicated E221i driver even) and after these, at some point the monitor loses its signal and goes dark again. In two unique cases, the monitor didn't go dark but instead had a rolling image (like a slow moving film strip). Pulling the power cable and letting any afflicted monitor sit for a lengthy period of time usually restores use but given time, fails once again. We're now switching them out with others in inventory to see if things stabilize. Can anyone comment if they, too, have seen similar issues with this monitor? For many years, we’ve used HP gear for all our computers and monitors (mostly) and have never seen this phenomenon before. Curious if there is a very small bad batch of these out there. Thank you in advance for any comments.

Re: Problems with several new HP EliteDisplay E221i's, lose signal

I have also experienced an issue with the EliteDisplay E221i flashing on and off.  It seems to be related to what is on the screen at the time if I clear the screen by moving windows to a different monitor then the problem resides.  I can move items back to the screen and it will act fine for a while then I will send items back to the screen slowly and when it gets too many open windows on it it starts to have the issue again.  It is using an HDMI input cable which I have swapped to prove it wasn't the cable.  It is connected to an EliteBook through a docking station.  I have tried a different docking staion with the same results.  I have Windows 7 Enterprise N service Pack 1 64-bit Operating System running on the system.  4 GB Ram, Intel(R) Core(TM) i5-4300U CPU @1.90GHz  2.50GHz.  Display adapter is the built in Intel(R) HD Graphics Family with driver version  If someone has an answer that leads to how to resolve this it would be appreciated.
