When purchasing this docking station it was recommended by the sales guy. I specifically mentioned that I had 3 monitors and would need HDMI for. This only has 2 x HDMI and 2 of another video input that doesn't allow for 3 x monitors to be connected. When we returned to the store to ask for a solution we were sold another adapter cable which also does not work. The idea of the docking station was to eliminate multiple cables having to be plugged into the laptop however we are still having to plug additional screens in. Other than that the docking station works fine and PB Tech is still my favorite store!
