The THX Optimizer is a quick and simple calibration tool that I have found gets the job done well enough for most of us non-fanatics. And it comes with a free movie!

Does the THX optimiser from a dvd work well for PC monitor?? Always thought it was for HDTV seams on SDTV tends to give too much blacks, contrasts tends to be a bit off what would be an equivalent for an old PC monitor (10 years) or old SDTV (15 years)?? Lots of different solutions on the net. Any good freeware? TV sets (SD or HD) use a different gamma. vs computer monitors. Also digital video uses 16-235 black to white where computer monitors use 0-255.
To play correctly scaled TV captures, DVD, Blu-Ray, etc a video player is required (e.g., MPCHD) to make levels and gamma shift for computer viewing. When these software players are used, the THX optimizer can be used to make fine adjustments.TV gamma skews levels detail to the dark end of the luminance scale where computer gamma is more linear.
