see (Multiple Monitors) but only on screen shows, therefore cant extended display RRS feed

  • Question

  • Have  Windows Vista 32bit ent. edition with SP2 on HP laptop 8530w with NVIDIA QUADRO FX 770 .

    work beautifully on two monitors in extended mode (each screen different view) with various versions of drivers (microsoft's and nvidia's) .

    SUDDENLY, can do it any more. on diaply properties instead of seeing two monitors as before, i see (Multiple Monitors) but ONLY ONE MONITOR below on the gray area. as a result, cant use extended display.

    see the picture attached. http://cid-e19fe6521bca5428.skydrive.live.com/self.aspx/New%20album/untitled.bmp


    can use single display or clone display.

    when selecting Dualview (Nvidia's extended display) it goes back to single blink.gif

    removed and install latest and older version of the drivers, both from HP and from NVIDIA and the defualt NVIDIA of microsoft's, nada.


    please help !

    thanks
