Video Card Works, but Windows says No Monitor Output

  1. Hey guys, I am starting to experiemnt with overclocking my nVidia 8800 GTS 640mb. I was reading a guide from and they told me to download a program called, ATiTools (which works with nVidia cards btw). When I try to overclock I get this message,

    "The video card you selected for overcloking does not seem to be used by windows...visual testing has been disabled...To fix this go to display properties, settings, and enable monitor output for the card."

    Well I followed the instructions but I can't seem to find anything to fix this situation, am I missing something very simple or is this a larger problem? Any help would be much appreciated!
