QuickGamma allows you to calibrate your PC monitor on the fly. The optimum gamma setting for your monitor can then be saved and automatically restored each time Windows starts.
The Gamma correction is accomplished via the graphics card color look up table (LUT).
The relationship between the input signal and the luminance of a monitor is not linear but exponential with gamma being the exponent. Monitor gamma values usually range between 1.4 and 3.2.
Because only a gamma value of 1 resembles a linear relationship, a gamma correction is necessary to achieve maximum reproduction quality. A gamma value of 2.2 has become the de facto standard for Windows, the Internet and the digital photography.
Under Windows the graphics card drivers try to correct the gamma value of a monitor to 2.2. This does not work most of the time because not only the different monitor brands and models have different gamma values, but also the same models from the same manufacturer sometimes differ in gamma value considerably.
Given these facts it is obvious that a general gamma correction can not be accomplished. Each monitor needs an individual correction.
With QuickGamma you can calibrate your monitor to a gamma value of 2.2 the easy way. More information and detailed instructions on how to use QuickGamma are available by pushing the Help button in QuickGamma.
