Some Intel NUC models offer displayport 1.2 output. You can chain qty 4 1920x1080 (or 1920x1200) monitors with DP. As for KVM, Avocent has many models, some of which are 32ports or more (KVM over IP). But wondering how this will work because the video outputs are hooked up to monitors, so the KVM will only be used for keyboard & mouse and not video? BTW, this is going to be a heck of a wiring job (power, network, video, other cables). Also take note of power, will need several separate circuits. Which also brings up the question: will be using UPS and generator for backup?. Some commenters suggested virtual servers running virtual desktops with thin clients as endpoints on each monitor, this will work but will be a bit more expensive and harder to implement/manage. Also, unless virtual server infrastructure is redundant (i.e. clustered, etc.), this represents a huge single point of failure. But all of this can be made more redundant if the $$$ is there. Thanks.
