Matrox TripleHead2Go breakout box

Matrox TripleHead2Go breakout box Display Port edition. This is a breakout box that allows a single monitor output to be split across 2 or 3 playback devices (projectors, monitors, etc). Requires Matrox software to be installed on the video source computer. If you are using two monitors (outputs) (and not three), use outputs 1 and 3. At least on the High Sierra OS, the Matrox Powerdesk software will not detect all the monitors and will give a message to this effect. In "Displays" under "System Preferences", though, the two monitors should appear as one double-wide display.
