Gamma Control

Gamma Control is a very easy to use software solution designed to help you adjust gamma settings on the go, using keyboard shortcuts exclusively.
Especially useful if you're playing games on your computer and you need to adjust gamma without quitting the game, Gamma Control adopts a minimal interface, with just a few options and intuitive tools.
The program doesn't look good at all, that's true, but behind that ugly interface you shall quickly find the gamma adjustment utilities that could help you a lot in many important moments.
The main window of the app is actually so simple that it only displays some basic options, letting you launch the program at Windows startup, run and remain minimized to Tray and save gamma adjustments.
But what's more important is the information that's hiding under the “Options” screen. There are dedicated keyboard shortcuts to turn gamma up and down, set it to default, quickly switch to two different profiles and force the monitor into sleep mode.
Of course, each hotkey is fully configurable, but all of them can only work by pressing CTRL + ALT + a user defined key.
Supposed to run all the time and keep an icon in System Tray, Gamma Control is far from being a resource hog, working flawlessly on all Windows versions.
All things considered, Gamma Control is indeed a handy lightweight utility and it's a shame that it doesn't boast a more appealing interface. It serves its purpose however and even integrates a basic manual to provide assistance to those who can't figure out how to use it.
