Can anyone recommend an application that will automatically dim my monitors when it gets dark at night?

This could be accomplished using a cronjob with a simple script (at least under Linux). Maybe I'll write such a thing when I get home. –  Bobby Jun 7 '10 at 9:54

One app to try

f.lux™ Better lighting...for your computer

it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

Available for XP/Vista/7, OSX and linux

I can't recommend F.lux enough! –  Canha Aug 3 '12 at 20:53

At least the OS X version of Flux doesn't currently allow changing the brightness. The only thing it can do is increase the color temperature at night (or day). –  Lri Aug 3 '12 at 22:42
    
It appears the Windows version also doesn't do brightness dimming, but just color temperature. Both together are essential though, and f.lux at least has done the complicated and rare half of doing the color side - automatically no less. The question is, what app can automatically DARKEN the screen on a schedule (and/or with hotkeys for up/down)? –  foregon Jun 28 at 9:25

A linux app

Redshift

Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

You can use Dimmer for Windows to lower the brightness itself between 5% and 95% opacity.

f.lux is great, but it just doesn't do enough; you can use it in combination with Dimmer, though.
