Run a Matrox TripleHead2Go with a Powerbook G4

Shortly I bought a Matrox TripleHead2Go (analog) Extension Module and discoverad afterwards that it isn’t supported to work with my new MacBook 2.16 GHz Intel Core 2 Duo nor my PowerBook 1.67 GHz PowerPC G4 with 128 with ATI Mobility Radeon 9700, 128 MB. I expected at least the DualHead Mode running on the new MacBook. (According to the compatibility page.) But in fact it doesn’t. There is a new driver for Windows to run the TripleHead as Dualhead (strange enough), but none for Mac OS X. I got frustrated.
Really? Is that possible, such a lack of support for the Apple community? I couldn’t believe it so i wrote a mail to the Matrox Support team. Here the friendly but useless answer:
Thank you for your email. Actually, it is mentioned on our website the Mac models that were tested and are supported with the TH2Go. PowerBook G4 is not on the list, it means that it was never tested and no plan to support it. MacBook can only support the DH2Go and not the TH2Go as you can see in the table below. It is a hardware limitation of the Intel GPU and there is nothing we can do to make it support the TH2Go. The TMET utility to allow TH2Go to work in dual head mode is only available for Win2000/XP.
But still, after that i couldn’t believe that my Powerbook with 128 megabyte of VRAM can’t access the card. Today I gave it a retry. I set the Hz down to 60 and voila. It is working. I didn’t test through all the resolutions. I’m already happy with three times 640 x 480 for VJing. The next shows will feature a TrippleHead-setup. Watch out!
