--- Comment #14 from Jan Burgmeier jan.burgmeier@unicon-software.com --- Thanks for your effort so far.
I have two monitors connected so I get a picture, but the error also occurs if only the NEC monitor is connected.
The NEC monitor is connected directly with DP and the second monitor is connected with a DP->DVI Adapter.
I think it has somehow to do with the NEC as other monitors work fine.
