QuickGamma is a small utility program to calibrate a monitor on the fly without having to buy expensive hardware tools.

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 monitor gamma value of 2.2 has become the de facto standard for Windows, the Internet and the digital photography. Under Windows a gamma correction is already automatically applied. This yields a linear luminance distribution for monitors with a real gamma of 2.2. Because most computer monitors do not have a real gamma of 2.2 an additional correction is required. With QuickGamma you can calibrate your monitor to a gamma value of 2.2 which in conjunction with the automatic gamma correction yields a linear luminance distribution for every monitor.

• Download QuickGamma

  • QuickGamma V3 can be downloaded from the websites below. Just click on the image of your choice to get the download started.

    

    

• Download Runtime Libraries

  • QuickGamma requires the 32 Bit runtime libraries mfc90u.dll and msvcr90.dll to be installed. These libraries are part of the "Visual Studio C++ 2008 redistribution packages", which can be directly downloaded from Microsoft.

    Both, the "Visual Studio C++ 2008" and the "Visual Studio C++ 2008 SP1" runtime libraries are required!

    

    

• Installation

  • To install QuickGamma, simply open the downloaded QuickGamma installation file. If the required Runtime Libraries are not yet installed, the appropriate Microsoft Visual C++ 2008 Redistributable Package must be downloaded and installed by opening the downloaded installation file. That's all, QuickGamma is now ready to use.

    If a previous version of QuickGamma is currently installed, open that version and write down the Red, Green and Blue gamma values before installing the new version. Once the new version has been installed, open it and enter the previously written down Red, Green and Blue gamma values. Make sure to read the new help file. There are some differences in the user interface compared to the previous version.
