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.
