There is a solution that I think you would find suitable if the distance is within spec. I found a company that sells a distribution system for linking up to 16 displays @ 500 feet away. Cat5 Ethernet cable would bring the video signal from the Server room and would connect to the main hub which can be hidden somewhere. Then each monitor would have a satellite unit that would also connect with Cat5 and could be mounted somewhere on the display.
Hope this helps,
