I had a question regarding the availability of monitors that can be powered via 802.3at that was closed as off topic recently: https://serverfault.com/questions/256868/does-anyone-know-of-a-19-or-larger-monitor-that-runs-over-poe
The message states: "Questions on Server Fault are expected to generally relate to system administration, servers, or professional desktop IT in some way, within the scope defined in the faq." The FAQ states that questions about servers, networks or desktops in the workplace are legitimate, and this question most certainly falls under that scope.
