Matrox Graphics used this week's Game Developers Conference (GDC) in San Francisco to introduce the TripleHead2Go Digital Edition. The device enables users to hook up to three DVI-based displays to a Mac or PC using a single dual-link DVI connector. Coming in the second calendar quarter of 2007, the TripleHead2Go Digital Edition will cost £195 plus VAT.

The TripleHead2Go Digital Edition is the latest of Matrox's Graphics eXpansion Modules (GXMs). It works in tandem with your computer's existing video RAM and display output to enable you to create a virtual display up to 3840-x-1024 pixels. One dual-link DVI input is broken into three DVI outputs using a small black box that's powered by USB.

At GDC, Matrox demonstrated this by setting up several PCs in a panoramic view using three ViewSonic displays each for output. One system was being used to show an auto racing game, the other a standard Windows desktop. But the system also works on Mac OS X v10.4 or later.
