I am using a main tv for my front screen using a display port to a HDMI pigtail and the other 2 monitors to just the other 2 display ports. I get the main going anf the right one but it is not an extended screen per say but a copy of the front one and the right screen is just black with not sig. I have a Gigabyte Z97x G1 mobo, XFXRS5700XT Raw II, plenty of ram, and a I7 4770K. monitors are just basic HP's and the Tv is a cheapo Element flat screen (LED OR LCD I dont remember off hand to be honest). Thanks
