I would strongly suggest you disable Image Sharpening, or at least reduce it to the lowest possible setting you can tolerate, and consider turning it off when playing games. It adds unoriginal information to the image. Things might seem a little blurrier but that's the native picture and how it was intended to be seen.

There's also a really good DVD out there called Digital Video Essentials (and an HD version I hear now too) which helps you do professional quality calibration of your TV settings and given how the "contrast" is really a combination of your TV settings and your video card settings, it takes some work to get it right.

In general I've found that the DVE disc calibrates my TV for an excellent NTSC movie quality signal, great for watching DVD movies, but that same image is a bit dark for gaming. So I have two Nvidia profiles.
