If you use a multi outputs card ( ATI 5700 for ex ) as an extended desktop, does it works just like it does for the triple head???
Or the double an tripple head are the only way to use more than one physical output???

We have had some success simply starting up multiple instances of MadMapper. One for each output on the graphics card(s).
There is a certain performance penalty though. And a few frames of lag so that the outputs are not in perfect sync. But for some uses it works OK.

Yes the only one solution actually is to use multiple instances of MadMapper (copy of the application) or use Triplehead and Dual head.

One important thing Minimize all your currents madmapper application when your setup is ready will improve a lot the performances !

Best,

Yea but don't click the yellow 'minus' sign in the window to hide it in the dock. I momentarily freaked out during a performance because this causes dropped frames.
