i've got a D33217GKE with two insignia 32" HDTV's hookup to the two HDMI ports on the Nuc. i've still got one usb 2.0 port that is not occupied... can i use it to hook up yet another two 32" insignia HDTV's to it. the insignias all have VGA, HDMI and displayport capability. i was think maybe a displayport usb 2.0 verision video adaptor, or something similar. i'm running linux (Ubuntu 14.04 LTS) OS on th box and am willing to spend some time fussing with xrandr for the proper configuration. i'm just wondering if there is any hope of having all four monitors hooked up the the NUC. i've done quite a bit of research and haven't found anything definitive. so any help would be appreciated.
