Currently I am at my parents their house so only my 15" laptop screen available, when I am home again I'll check it out and post some screens (after Christmas).
It is true that I connect both my monitors on 1 card, and the control panel says my laptop screen is connected to that one as well, which makes it impossible to use 3 screens because "only two screens are supported by this GPU". Trying to use the other card for one of my screens seems impossible somehow..
Triple monitor setup? That is a huge panoramic for a desktop.
