I have a Samsung Syncmaster 2233SW 22" Monitor. Every time I turn on my PC my monitor turns off and on a few times each time switching between Syncmaster 2233SW and Generic non-PnP Monitor (as seen in the screen resolution setting window) eventually stopping at Generic non-PnP monitor...after a while it starts doing it again..I have tried removing the device from control panel and let it detect it again, only to see the same problem again..
