The relationship between the input signal and the luminance of a monitor is not linear but exponentialwith gamma being the exponent. A gamma value of 2.2 has become the de facto standard in Windows, theInternet and the digital photography. This means that only monitors with a gamma value of 2.2 will producea correct output. Despite the fact that the gamma values of monitors have improved over the years, manymonitors still have a gamma value that deviates more or less from 2.2. A correction is therefore requiredto achieve optimal results. The monitor gamma can easily be corrected to 2.2 using QuickGamma. Moreinformation and detailed instructions on how to use QuickGamma are available by pushing the Help buttonin QuickGamma.
QuickGamma Version 4 does not work on any Windows versions prior to Windows 7 and consists of the programQuickGamma.exe, the help file QuickGamma.chm and the printable help file QuickGammaHilfe.pdf. All other files thathave been part of previous versions of QuickGamma are not required anymore because QuickGamma Version 4 now utilizes theWindows 7 Display Calibration feature.
Microsoft has introduced a new feature called Windows Display Calibration into Windows 7. Detailed information about howto use the Display Calibration can be found at -US/windows7/Change-color-management-settings.Besides offering a visual calibration wizard, this feature supplies a LUT loader, which automatically loads the LUT at systemstart up and whenever else the LUT needs to be reloaded (after waking from Standby or Hibernate for instance).The LUT is a hardware based Look Up Table in the graphics card and provides a means of input value to output value mapping forthe RGB pixel values and thus can be used to implement a Monitor Gamma correction.
Apple has been using the LUT since many years for its operating system built in color management. In fact, Apple has registeredthe private ICC Profile tag video card gamma table (vcgt) with the International Color Consortium (ICC). This tag is used in adedicated Monitor Profile and holds the gamma values, which are then loaded into the LUT by a loader program.
Hardware based Monitor Calibration Systems also use the vcgt tag, which in this case contains the correction data to achievethe monitor calibration. Because Windows did not provide a LUT loader, each calibration program had to provide its own LUT loaderprogram. This was working fine for quite some time until Windows came up with Standby and Hibernation. Unfortunately, the LUT loaderprograms were unable to cope with those Windows features and thus the LUT was reset each time when resuming from Standby orHibernate.
To make things worse, the graphics card manufacturers came up with programs that were installed along with the graphics carddriver and allowed the user to play with colors and gamma. These programs were also resetting the graphics card LUT at systemstartup, which caused a race condition with the LUT loaders of a Hardware based Monitor Calibration Systems. The program that wasloading the LUT last won...
All it takes to utilize the Windows 7 LUT loader is to install a Monitor Profile with a vcgt tag containing the LUT data andto make this profile the default profile for the respective monitor. Because such a profile is not available by default, theWindows 7 Display Calibration feature is not active by default and must be activated manually.
To install QuickGamma, simply open the downloaded QuickGamma installation file. If the required RuntimeLibraries are not yet installed, download the Microsoft Visual C++ 2010 Redistributable Package (see linkabove) and install it by opening the downloaded installation file. That's all, QuickGamma is now ready to use.
The first and most important tool reloads the LUT after resuming from standby/hibernate.This tool comes in handy when calibration tools like the X-Rite i1Display 2 (iMatch Version 3.6.2 software)do not reload the LUT upon resuming from standby/hibernate. This tools is not required in QuickGamma Version 4 anymore.The next tool lists the current LUT for any attached monitor.
