To those with the recalibrate graphics problem:
I had this, too, and I found a solution in another thread here. There are two screens installed on the system, one correctly and a default one. You have to recalibrate something in the registry with the NVidia drivers, but I don't remember everything. The most important thing is that they want to run in two-screen-mode which has to be disabled by setting a new line "TwinViewDisabled" set to "1", in the
"HKey_Local_Machine\Software\NVidia Corporation\Global\System" folder. You should search the forums again, though, because I'm not sure whether that was all.
