If you use different monitor brightness and contrast for day and night, for work and playing games, watching movies, and you adjust the monitor by either using its OSD menu, or using a software that provides some slider bars for you to drag. If you are tired of doing it, now it's time to change.
No longer OSD menu, no slider bars, just click to switch.
With Monitor Brightness Switch (MBS), you can switch your monitor to predefined display modes with simple clicks. Those display modes are defined by yourself for your monitor, each of them contains specific brightness and contrast for a different environment or situation.
