Hi
this thread to try to clarify what the Display Port Edition of the Matrox Triple/Dual Head supports and what not.
As far as I can see, it only accepts DP in its input, there is no converter that will work.
This one that Dottore was talking about:
What exactly are you trying to accomplish with your setup? Why not just get the digital edition? It has 1 DVI and 1 VGA input, and 3 DVI outputs.
It looks like that DP to DVI adapter is single link. Meaning that the highest resolutions of the TripleHead won’t be supported with that.
If you have a displayPort output you can get 3x1920x1080 from the DP tripleHead, but this will only work with a straight displayPort cable.
I know from personal experience that VGA into the TripleHead Digital Edition supports a max of 3x1024x768, and HDMI (converted to DVI) only supports 3x800x600.
Dual Link DVI is needed for the max resolution of 3x 1280x1024.
I seriously doubt you will be able to convert DVI to displayport and get the displayPort resolutions. You will probably be limited to the DVI resolutions.
