Triple Screen work, but not mouse

[Pierrick584]

Greetings, i am trying to play the game in a triple screen setup, and i have experienced an issue.
when i open the game, mouse seems not to work at first, then if i escape the few first messages and get to the profile selection, i can see the mouse in my right screen nearly at full right (about 100~ pixels of the right side) moving only vertically, and if i recall, with the cursor slightly glitched. here's a few details about my config..

EVGA Geforce 550TI x2 (not in sli, as i cannot make it detects my 3 screen yet ><)
Amnesia in 5760x1080 (3x 1920x1080)
Every graphic option maxed out
Nvidia Proprietary driver 285
