OK. So I am trying to run 2 1920x1200 24" monitors via the Matrox DualHead2Go Digital Edition, achieving a "resolution" of 3840x1200. The old Macbook Pro (running NVIDIA GeForce 8600M) could do this, and my old HP Notebook (running NVIDIA GeForce Go 7400) could do this. However, the new Macbook Pro cannot. Obviously something is not right here. It is completely illogical that NIVIDA could make a better, faster GPU in the same product line that can't handle this pretty trivial task, so that's out. To my knowledge, the "resolution" 3840x1200 isn't exactly a "real" resolution; it is basically just 1920x1200 done twice. My claim has been forwarded to the Apple Engineers, and they suggested that I get the Dual Link DVI cable. I know this cable is for running 30" monitors at 2560x1600, but since my old computer didn't need a Dual Link and neither did the old Macbook Pro, I don't think this is the solution. Also, isn't 2560x1600 technically a higher resolution than 3840x1200? The only logical explanation really is that this is a driver issue, and since the new Pro's must be equipped with the latest drivers, it seems that rolling back the drivers should work. So, I am wondering the easiest way to do this. If this is not a great option, should I try to run the displays via Windows XP via VMWare Fusion (because it's presumably way easier to roll back drivers in Windows) ? Any and all help is greatly appreciated. Thanks.
