How do you change display-related settings, like brighness or contrast on a Windows device? Do you use Microsoft's preferred way of doing so, by going to Settings > System> Display? Do you use the controls of the display for that, or something else entirely?
Windows 11 might not even display options to control the brightness or may have locked it. That is one use for the tiny, decade-old application Gamma Panel.
Gamma Panel to the rescue
Gamma Panel may be old, but it still runs on the most recent versions of Windows 11. It is a portable application with a size of less than 120 Kilobytes. You can run it from any location and it displays its screen right after start.
Use the three sliders next to Gamma, Brightness, or Contrast to change the values. The changes take effect immediately and it is real easy to make the display brighter or improve the contrast. The reset button restores the defaults, which can also be handy.
While that would make Gamma Panel a great app for Windows already, it comes with a kicker. You can save adjustments as color profiles and assign hotkeys to them. This enables you to switch between different color profiles with just a hotkey. Say, you want to increase the brightness and gamma while playing games, to see "more". You could create one color profile for that and assign a hotkey to it. Save another for the default setting, and you are good to go.
Whenever you start a game, activate the brightness-improving hotkey and you will notice the difference immediately. Once you are done playing, activate the hotkey for the default color values and these are applied again.
The website of the developer of Gamma Panel is no longer available. You can download the latest version from third-party download repositories, such as that from Softonic (Ghack's parent company).
Gamma Panel is not the only app that offers the functionality. I reviewed Gamminator back in 2016. It is an open source application that focuses on Gamma only. Still, it is updated regularly and should work fine on recent Windows installations as well.
