Matrox has announced its new DualHead2Go and TripleHead2Go peripherals with Macintosh support. The devices are small external boxes that can be connected to the video output of the Mac, allowing two or three displays to be used simultaneously.
The DualHead2Go and TripleHead2Go are priced at $ 169 and $ 299 respectively. Both devices are part of the Matrox Graphics Expansion Module (GXM) product line. They are the size of the palm of your hand and include one VGA input and two or three VGA outputs.
Devices are recognized by the Mac independently depending on the number of monitors that are connected to them. For the Mac, the junction box appears as a single ultrawide monitor that supports resolutions up to 2,560 x 1,024 pixels or 3,840 x 1,024 pixels, respectively. The connection box splits this signal between the two or three connected monitors.
Support is limited to a number of supported Macs (such models are listed on the Matrox website, focusing on computers based on Intel processors). The use of a mini-DVI to VGA adapter is also required.
The Mac Pro already supports more than one display because multiple graphics cards can be used with support for two DVI connectors, so even more displays can be used by installing multiple graphics cards in the Mac Pro’s PCI Express expansion slots. However, MacBook, MacBook Pro, Mac Mini, and iMac users are limited to connecting a single external display, so these displays offer these users the ability to use more displays simultaneously.
