I recently started experiencing a problem with a Java application locking up when moving windows from the laptop screen to an external monitor. One of the things we discovered during troubleshooting is that I am showing 2 Display Adapters:
Intel(R) HD Graphics - running the Laptop Screen
NVIDIA NVS 3100M - running the external Screen
Is this correct? I now also know why when using the NVIDIA Control Center it only shows the one monitor.
