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.
Adjust external monitor brightness in Windows 10
- Download Monitorian from Microsoft Store.
- Launch the Microsoft Store app and search for Monitorian app.
- Click on the Install button.
- Once installed, launch Monitorian.
- You can also install Monitorian by downloading it from Github. In my case, downloading and installing directly from the Microsoft Store worked flawlessly.
How to use Monitorian
Click the Start button and open Monitorian. Latter, click the System Tray icon and click on the Monitorian app icon.
Clicking on the app icon will show all the displays connected to your computer. To adjust the brightness, simply drag the slider to increase and decrease the brightness. You need to adjust the brightness for each display individually.
If you want to change the screen brightness of all the monitors in unison, you can do that as well. Right-click on the Monitorian app icon in the System Tray and select Enable moving in Unison.
If you are using a laptop with a secondary monitor, the app will show your laptop’s display as a Generic monitor. In contrast, the secondary monitor will have its model name associated with it to avoid confusion.
What to do if Monitorian is not working on your computer?
If the Monitorian app is not recognizing your secondary display, make sure the DDC/CI support is enabled. Also, make sure the adaptive brightness or Bright Intelligence features is turned off.
Note: The following steps are for the BENQ Monitors. Refer to the monitor manual if you are using any other monitor.
- Press any of the physical buttons on your monitor.
- Select the Menu option.
- Go to the System tab using the physical buttons.
- Select DDC/CI > ON.
- Save the changes and exit monitor settings menu.
Exit and relaunch Monitorian and check if the app recognizes your secondary monitor.
Disable Bright Intelligence
- Press any control button on your monitor.
- Select the Menu option.
- Go to Eye Care > Bright Intelligence > Off.
- Exit the settings menu and check for any improvements.
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.
Adjusting the external monitor brightness using the control button is a cumbersome process. This is where Monitorian shines. It is free to use, supports up to 4 monitors and offers unison and individual brightness adjustment control for all the monitors.
