As a Tech with 35 years experience, I'd LOVE to hear how you can get 'feed back' from a monitor about it's gamma curve.

(LCDs - DVI pinouts) And I seriously doubt that internal monitors have it either. From reading Bud Simrin's and now jackl73's responses, it's got to be, at best, an April Fool's joke, at worst, a virus. DON'T Download!
