How to Change Screen Brightness in Windows 10 Desktop (Monitor)

If you are searching for an easy way to adjust monitor brightness, follow this straightforward trick to change screen brightness in Windows 10 desktop.

On a laptop, it’s very simple to control screen brightness. All you have to do is drag the slider in the Notification center. Most laptops even have dedicated buttons or secrets of decrease or increase screen brightness.

However, with regards to the desktops and external monitors, you will not find any options whatsoever within Windows to alter monitor brightness. It has more to do with monitor manufactures than Windows.

That said, there are several methods to change monitor brightness using Windows software. Here are a few of those ways you could try.

How to Adjust Brightness on Windows 10 Desktop

To change screen brightness in Windows 10 desktop we will use a free and light-weight software called Twinkle Tray.

Download Twinkle Tray from Github.
Double-click on the exe file and install it.
Open the application by searching for “Twinkle Tray” within the Start menu.
After opening it, it will be available in the taskbar. Click it.
Once you click, you will notice a brightness slider. Drag the slider increase or decrease monitor brightness.

That’s it. It is just that easy to adjust monitor brightness without needing the computer monitor buttons.

Optional Twinkle Tray Settings:

If you wish to, you are able to assign keyboard shortcuts to increase or decrease screen brightness. To achieve that, open the Twinkle Tray slider on the taskbar and click on the “Settings” icon.

Visit the “Hotkeys” tab and assign the laptop keyboard shortcuts as needed. In my case, I set Ctrl + F12 to increase brightness and Ctrl + F11 to decrease the brightness on all displays.

You may also configure the app to automatically adjust the brightness based on time. For instance, you may want the computer monitor to become bright in the evening and dim at night time. If that’s the case, go to the “Time adjustments” tab and click on the “Add a time” button to set the timings.

Other ways to regulate Brightness

If the above method did not work or you are searching for an alternative, here are a few.

Use Monitor Brightness Buttons

The easiest and sure-fire way is to use the computer monitor buttons. Usually, most monitors have dedicated Brightness buttons.

On some monitors, the brightness controls might be buried within other menus. For example, on my small Dell monitor, the brightness controls have been in the primary menu. So, basically want to change the brightness, I have to first open the menu, select the Brightness option, and then change it using the down or up arrow buttons.

Based on your monitor, the best way to change monitor brightness may differ. If you cannot find the option within the monitor menu, check out the monitor manual. If you’re like me and have no idea where you’ve stored the monitor user manual, don’t worry, you can generally find the user manual online.

Just search for “<your monitor model> user manual”. Replace “your monitor model” using the actual monitor manufacturer name and model no ..

If you are frequently changing the monitor brightness to complement the lighting conditions, depending on your monitor you may be able to create dedicated shortcuts inside the monitor menu. Again, taking my Dell monitor as an example, it lets me create custom shortcuts so that I can change the brightness with just two button presses.

You might have to dig through the menus or the monitor’s user manual to find away out to create custom shortcuts, though.

Use Software from Monitor Manufacturer

In addition to the buttons on your monitor, most monitor manufacturers create and release a companion software that allows you to better manage your monitor.

For instance, Dell includes a simple software called Dell Display Manager that lets you do a number of things like adjusting screen brightness, adjusting screen color depending on the active application, changing resolution, etc. With my case, to alter the desktop monitor brightness in Windows, all I must do is click the application icon and drag the brightness slider. It’s that easy.

Moreover, the good thing about using first-party software is that they will add additional functionality to your monitor that is otherwise unavailable. As well as, using proper software eliminates the necessity to cope with the clunky monitor buttons or terribly designed monitor control menus.

Just go for your monitor manufacturer’s official website to check out any available companion software.
