Hello @paulozinga,

If you have a MacBookPro with a Thunderbolt port, be sure you got a TripleHead "Digital SE" or "DP Edition". The TripleHead "Digital" (with only DVI input/outputs) doesn't work on such systems.
If you got a simple MiniDisplay port, it's ok.
Please refer to Matrox website.

Moreover, the "Intel HD 3000" graphic card isn't the right one for the MacBookPro : it's the economic graphic card. Be sure to run gfxCardStatus and check that you switched to the performance graphic card.

Hello @paulozinga,

I think your Matrox card is not suitable for your MacBookPro: please refer to Matrox website to check this.
If you have a doubt, write a question to Matrox support, they are quite reactive.

This is indeed the case. You need a Dual Link adaptor for any resolution over 2500px or so. If you lower the resolution going into the TH2Go to say 3x 800x600 or even 3x 640x480 you'll get a normal DVI cable to work ok.
