Over time, your LCD or CRT monitor will gradually fade in brightness and contrast. This fading is inevitable, because the backlights for LCD screens eventually fade, and the photo-reactive substrate on CRT monitors eventually degrades.
ScreenCleaner Pro rectifies this situation by altering the gamma of your monitor to compensate for monitor degradation, so it will look as good as new. Don't toss out that old monitor, just run ScreenCleaner Pro on it, and watch your old monitor gain a new life.
