I am looking for information to configure my PC using the Matrox tripleheadtogo digital. I want to be able to get 1920x1080 x 3 with three 22-inch monitor.
Sorry, TripleHead2Go is limited to 1680x1050 x 3 :!:
Since you have no budget limitations (lucky you!), you could dump those 4850s and simply get a Radeon 58xx or 69xx and a DisplayPort adapter, and use AMD Eyefinity to game at 5760x1080.
Feel free to visit the Eyefinity subforum for more info: http://www.widescreengamingforum.com/forum/viewforum.php?f=64
