Question: Second monitor not recognized

All available NVidia drivers are installed if the second monitor is not detected immediately. For two weeks I have used Win 7 connected, the second (Samsung SyncMaster P2470HD) via VGA. My primary monitor (HannsG HG171A) is via DVI (PC, Computer, Display) video

In my PC, an NVidia Geforce 4 runs perfectly on this PC, also in parallel.
