@all Macbook pro (Unibody) users
After much struggle and gotta zapped by the wisdom of God, I manage to get my TripleHead2Go Digital to work up to 2 x 1920×1080. This is how I did it.

1) Set the display mode for the TripleHead2Go either on the mac with Matrox PowerDesk. The software didn’t work for me on the mac thus I plugged it into bootcamp and set it in Windows instead. This will set 4 set of EDID which tells the connecting mac what resolution it will support. I set one of them to be 3840×1080.

2) Plug in Dual-Link DVI adapter. (Both USB and Mini Displayport).

3) Plug in USB power cable of the Matrox box.

4) Connect the DVI cables of the monitors to Matrox box output (1 & 3 if your doing dual-monitor)

5) Connect DVI cable of Matrox box input to the Dual-link DVI adapter.

6) Mac OSX will detect the box and start sending display information out. However more likely your monitors will be either black or corrupted. Don’t worry we’ll fix this in a sec. Set the resolution for the Matrox box that you require in Display settings. In my case I choose 3840×1080.

7) Unplug the USB power cable to the Matrox box. Wait a sec then replug in the USB power cable. The monitors should now have the correct resolution displays shown on them.

The important part is to powercycle the Matrox box after the OS has detected it. Hopefully others can their Macbook Pro higher than 2048×768. Last bit of info, I’m using a Macbook Pro 17″ (Unibody), Triplehead2Go Digital and 24″ Dell monitors. Cheers!
