In case you didn’t know, the TripleHead2Go and DualHead2Go are display adapters that multiply the number of monitors you can drive by taking a single video output from your computer and splitting it into 3 or 2 more displays respectively. With this new software utility Mac users can now make better use of these pieces of hardware, especially with the digital editions of these GXMs.
With OS X 10.4 or later and one of these two GXMs in the digital edition, and then this new Control Panel software Mac users can now get 1920x1200 on each of 2 displays or 1280x1024 on each of 3 displays. These displays can be mirrors, or copies, of the original display or can be used to extend your desktop across the extra monitors.
That means that with a laptop you could extend your desktop across 4 monitors or mirror it across 4 monitors, maybe for watching a movie or presentation. The software update is free, you just need a TripleHead2Go Digital Edition or a DualHead2Go Digital Edition in order for it to work.
