A:Answer On a Windows 7 Pro system I could only get 2 of the 3 displays active. Windows display properties shows all three screens, but one was always inactive. Trying to enable it, or even just clone one of the other two screens (which is actually what my client was after) did not work. VGA, DVI, and HDMI -- I could select any two. Was attracted to the fanless/noiseless design, and modest power needs of this one.
