I have two monitors from different manufacturers at work. This means that the brightness and color parameters on them are different. Of course, you can manually configure the settings on each of the monitors using the buttons. And you can do this using the application in a couple of clicks.

Twinkle Tray helps you quickly change the brightness settings for multiple monitors.
After installing the utility, a special icon will appear in the tray. When you click on it in the pop-up window, you can adjust the brightness of all monitors using the sliders. Parameters can be changed for each monitor individually or simultaneously.
In Twinkle Tray settings, you can set the automatic brightness change according to the schedule.
