How to Adjust External Monitor brightness without using control buttons

Windows 10 supports multiple monitors setup and offers features like Extend, Duplicate or Second screen only options. However, the users still can’t change the external monitor brightness in Windows 10.

Third-party software like Monitorian allows you to adjust the brightness of your external monitor and up to 4 monitors directly from the Windows taskbar. It is free to use the app; however, it requires a purchase if you are planning to use it to control more than four monitors.

In this article, we show you how to change your external monitor brightness in Windows 10 without using the monitor control buttons.

The Bright Intelligence feature in BENQ monitors, when enabled automatically adjusts the screen brightness according to the light conditions of the environment. However, this feature also prevents the Monitorian app from functioning correctly.
