Editorial review


Sean O'Reilly Senior editor

Generally, calibrating your monitor is a tedious job. Even with the display calibration function that was introduced in Windows 7, things don’t get much easier. QuickGamma was developed to offer an alternative solution for this task.

QuickGamma is a simple tool that will allow you to calibrate your monitor with the help of the Norman Koren's gamma images.
The program allows you to modify all the values (red, green and blue) at once or to change them individually.

The latest version of QuickGamma will only work with Windows 7 and Windows 8. Once you’ve achieved the result, the program will automatically save your settings as the default profile for the monitor.

Although the graphical interface of QuickGamma can be considered quite intuitive, it has a big disadvantage. You can only increase or decrease the values in increments of one.

Furthermore, you cannot manually insert the desired values, so you will have to waste some time even if you already know the exact number that is needed.

Personally, I think that QuickGamma is a good solution for everyone in need of such a program. This minimalistic tool comes without a price tag, so, there’s nothing to lose by trying it out.


  • It helps you quickly calibrate your monitor.
  • Very effective for fine tuning.
  • The calibration images are better than the ones that Windows provides.


  • You can only modify the values in increments of one.
  • You cannot manually insert the desired gamma values.
  • If you have eye problems, this program can cause nausea.

What's new in version 4.0

QuickGamma Version 4 still contains Norman Koren's excellent gamma images, but now creates a monitor profile with a vcgt tag containing the LUT data. The profile is automatically installed, defined as the default profile for the monitor and the Windows 7 Display Calibration feature is automatically enabled. There is no need for any supporting programs anymore because QuickGamma Version 4 is all it takes to achieve a good visual monitor gamma calibration.

Publisher's description

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. 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.
