Dimmer - Adjust the brightness of LCD/TFT/LED displays, screens and monitors

Brightness control software for your monitor

Dimmer is a small and free application designed to help control the brightness of your computer screen, specially to reduce the brightness beyond what the hardware alone is capable of. This becomes very useful when you are in total darkness and the minimum brightness from your display or screen is still too much. It can dim all screens and monitors; LCD, TFT and LED backlit types (even CRTs).

Dimmer will not damage your screen or monitor in any way, if anything, it might actually save the backlight and consequently, energy, by making it emit less radiation. To note is the fact that most desktop screens are actually capable of reducing the brightness levels quite low, the same is not true on almost all laptop, notebook and netbook displays. Dimmer was conceived to work on all versions of Microsoft Windows.

Screen brightness adjustment the easy way

The need for this program came about because I do a lot of work at night and with minimum ambient light in the room, or (more often than I would like) in bed and my laptop (all of them) output a great deal of light even in the lowest setting. This was damaging to my eyes and I couldn't work well. So one day (back in 2004) I decided to develop Dimmer and solve this problem. I can now dim the laptop display to suit my needs and can finally work through the night without a problem. Your monitor brightness can be easily adjusted and the program sits in the system tray for your convenience.

Another convenient feature is that Dimmer does not require installation, its a portable application. Simply extract into a folder of your choice and run. The program stores its settings in an XML file (again for your convenience) in the program folder so the Windows Registry is not used. When no longer needed, just delete the folder and you are done. Dimmer options can only be accessed from its own icon located on the system tray (next to the task-bar clock). When it runs, it will dim the brightness to the level it was last used. The option to close/exit is in the context menu you get by right-clicking on Dimmer system tray icon.

Dimmer has been much acclaimed for its simplicity as the best dimming software for portable displays, screens or monitors and it will be even be better in the next version. Feel free to recommend it to your friends and family and you may link to this page if you wish. Hope you enjoy and find this software useful.
