Excerpt of article text...
If you use REALbasic for programming games or utilities, then this plug-in should be in your plug-in folder. This plug-in has one use, and it performs that function admirably: changing the monitor's gamma.
When monitors started being used extensively, it was discovered that the image that should be displayed and the one actually displayed were different. The electrons that are projected through the cathode ray tube to form the picture are slightly changed as they travel; they produce a darker image. The relationship between the darkness and electron deviation doesn't stay constant. Because of this phenomenon gamma was invented. When you change a monitor's gamma you change how the electrons come out of the cathode ray tube, making the picture lighter or darker. The same is true with LCD screens, but the pixels that make up the screen are made lighter or darker by a different mechanism.
Being able to change the user's gamma can be a useful function, if used properly. You can also use it for utility programs to fix your gamma. You could also play some very, very mean jokes on people with it, but I advise against it since it could result in some VERY threatening letters if you can't restore the gamma back to its original setting.
