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

QuickGamma version 4.1 does not run on older Windows versions, but only on Windows 10 or higher. QuickGamma is available as 64-bit and 32-bit version, both of which are included in the installation file. The appropriate version of QuickGamma for the installed Windows version is automatically installed. The QuickProfileLoader program is integrated into QuickGamma and is installed automatically. If QuickProfileLoader is already installed as a standalone program, it will be uninstalled automatically during the QuickGamma installation.

In addition to QuickGamma and QuickProfileLoader, the installation file also contains the help file QuickGamma.chm and the printable help file QuickGammaHilfe.pdf. No runtime libraries are required.

QuickGamma creates an ICC profile containing a VCGT tag with the data for loading the graphics card's LUT. The VCGT (Video Card Gamma Table) tag was registered as a private tag by Apple with the International Color Consortium (ICC) many years ago.

Hardware based calibration systems also use the VCGT tag, which contains the correction values of the display calibration. If you use Hardware based calibration, you can use QuickProfileLoader as a standalone program (see right) to load the graphics card's LUT.

The relationship between the input signal and the luminance of a monitor is not linear but exponential with gamma being the exponent. A gamma value of 2.2 has become the de facto standard in Windows, the Internet and the digital photography. This means that only monitors with a gamma value of 2.2 will produce a correct output. Despite the fact that the gamma values of monitors have improved over the years, many monitors still have a gamma value that deviates more or less from 2.2. A correction is therefore required to achieve optimal results. The monitor gamma can easily be corrected to 2.2 using QuickGamma.
