Just a FYI, if you are having issues with your Nvidia based HTPC display adapters, use the drivers found http://downloads.guru3d.com/download.php?id=10 . I do not know if this has already been posted somewhere in the forum. I tried searching for assistance with my Nvidia 8600GTS card and could not find what I was looking for. The card is connected to an Onkyo TX-NR906 and with the drivers downloaded from Nvidia's website, I could not get video (regardless of using Powerstrip). With the drivers I downloaded from Guru3d, I was able to resolve my video issues without the need for Powerstrip.
