Utility to improve the image of PC TV Tuner?

[bolido2000]

I heard some coworkers today that there is a utility that makes the image on a PC monitor more "TV like" when watching TV using tuner. Something about tweaking the display frequency of the image or something like that. Anyone knows what I am talking about?
