Brisync is described as 'Synchronize your external monitor brightness with built-in display. Application reads current brightness of your built-in display and passes it to external monitors via DDC interface. You can adjust brightness by menu in system status bar' and is an app. There are more than 50 alternatives to Brisync for a variety of platforms, including Windows, Linux, Mac, Android and Wayland apps. The best Brisync alternative is f.lux, which is free. Other great apps like Brisync are Twinkle Tray, Redshift, LightBulb and Red Moon.
iBrightness Tray is a little bit of a swiss army knife display tool as adjusting the brightness of your screen is just one of three main functions it has. The other two are turning on your screensaver at the click of a button and also the ability to turn off the display...
Brightness Controller allows you to software control Brightness, R, G and B of your Primary and Secondary Display in Linux.
NegativeScreen is a Windows application allowing you to invert your screen colors.
Brightness Controller easily allows windows users to set the brightness level of your LCD screen (It is very useful when your screen doesn't allow settings to be remembered without having to push many buttons on your screen!).
Trouble Sleeping? Device screen too bright even on the lowest brightness setting? Want to give your phone a warm look instead of that eye straining blue gaze you see at night? EasyEyes is the solution. By changing your device's color temperature, EasyEyes reduces eye strain...
Do you use your mobile phone after sunset? Do you use your phone within three hours of your bed time? If yes, then your device might be taking your sleep away. Bluelight from your mobile screens sends a signal to brain to wake up, and makes it difficult for us to sleep at night.
Screen Shader is a chrome extension designed to tint the screen a “cozy” orange color to reduce eye strain, eye fatigue, and restore day/night balance, while also providing a wide variety of settings for everyone's different tastes!.
This advanced Windows app allows you to alter the screen shading according to the time of day, which is great if you work outside the normal hours, or if you need a lift in the afternoon. You can set the colour tints and your awake and sleep times.
Night Screen is created for those people who spend a lot of time at night working.
Limit your exposure to energy-efficient lighting before bed. In addition to the LED screens in your electronics, energy-efficient lighting emits a lot of blue light.
Setting the color temp of the screen really only requires about 40 lines of C (80 or so all inclusive). sct is a crude utility which does roughly that. I’d say exactly that, but some of the calculations aren’t actually exact.
