Matrox TripleHead2Go Digital
 

While many are satisfied with having a single screen, imagine gaming across 3 displays with 180° vision. The Matrox TripleHead2Go Digital overcomes the shortcoming of a single or dual display setup and gives you the possiblity to connect up to three DVI based LCD screens with a total resolution of up to 5040 x 1050 for real surround gaming.
