Works on all monitors!
First of all this doesnt appear to change the backlight of an LCD, which is great. Because for that you can just use your default keyboard shortcuts. This app actually modifies the brightness on the video card, which means that all your (even non Apple) monitors will be affected by this. I have a really nice monitor that for some reason I cant change the brightness for, and this fixed my problem!
Great app!
