Multi-GXM Support

Drive More Monitors. Easily.

Connect multiple DualHead2Go or TripleHead2Go Graphics eXpansion Modules together and drive even more monitors. With the ability to drive up to six outputs (2x TripleHead2Go) in 3x2 or 6x1 or four outputs (2x DualHead2Go) in 2x2 or 4x1 configurations, Multi-GXMs can drive double the number of displays – all from the same system. Simply combine both units to a dual output graphics card and take advantage of the increased desktop real estate. Explore the possibilities!
