Matrox has released drivers that allows its DualHead2Go and TripleHead2Go monitor expansion system to work with Macs. Both are palm-sized boxes that connect externally to a notebook or desktop computer and allow users to attach two or three monitors respectively.

The company claims that the devices are simple to setup, as there is no need to open up the computer to insert parts or to replace any hardware or software. The operating system detects the DualHead2Go and TripleHead2Go like an ultra-widescreen monitor that supports resolutions of up to 2,560-x-1,024 and 3,840-x-1,024 respectively.

The devices' GXM technology then splits this ultra-wide resolution into two or three standard resolutions and sends the information to the attached monitors. Matrox says that the GXM maximizes the capabilities of the Mac by using its existing graphics hardware and software for all 2D, 3D, and video acceleration.

A list of compatible Macs can be found on the Matrox Web site at www.matrox.com/graphics/mac.

The Matrox DualHead2Go and TripleHead2Go cost £89 plus VAT and £170 plus VAT respectively.
