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

Brightness control software for all your monitors

Dimmer is a small and free application for Windows designed to help control the brightness of your computer screen or any other display. This becomes very useful when you are in near/total darkness and the minimum brightness from your display or screen is still too much. Dimmer can dim all screens and monitors; LCD, TFT and LED backlit types (even CRTs). The latest version supports multiple screens, displays and monitors with individual settings to adjust each screen.

Dimmer will not damage your screen or monitor in any way, if anything, it actually saves the backlight by making it emit less radiation. Most modern desktop screens and displays are actually capable of very low levels of brightness but the same is not true on almost all laptops, notebooks and/or netbook displays. Dimmer was designed to run on all versions of Microsoft Windows.

Screen brightness adjustment the easy way

The need for this program came about when working at night and with minimum ambient light in the room, or (more often than I would like) in bed, and my laptop outputs a great deal of light even in the lowest setting. This was uncomfortable and damaging to my eyes. So one day (back in 2004) I decided to develop Dimmer to solve this problem. I can now dim any screen, display or monitor to suit my needs and can finally work through the night without a problem. The monitor brightness can be easily adjusted via a slider and text input controls which are very easy to adjust and fine-tune.

Another convenient feature is that Dimmer does not require installation, it's a portable application. Simply extract into a folder and run. The program stores its settings into a file in the program folder (for your convenience) so the Windows Registry is not used. When no longer needed, just delete the folder and you are done. When Dimmer runs, it will dim the brightness to the level it was last used.

Dimmer has been much acclaimed over the years for its simplicity and as the best dimming software for displays, screens or monitors. 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.

This project is in active development. Contact me with suggestions, found bugs or critiques, all welcome.
