How to Change Brightness on Windows 11 [Step-by-Step Guide and Fixes]

Screen brightness is an integral part of using modern computing devices, especially when you look at the screen for long periods of time. It helps you reduce eye strain, improve legibility, and most importantly view content easily and efficiently.

However, depending on your settings, brightness can sometimes be difficult to manage, especially with the new UI changes on Windows 11. If you're having trouble adjusting the brightness, here are all the ways to manage it on Windows 11.

How to Manage Brightness on Windows 11

Single-monitor users can use the following methods to adjust brightness on Windows 11. This includes desktop systems using single monitors as well as laptops. let's start.

Method 1: Use Action Center

Action Center is the easiest way to access and adjust your PC’s brightness.

Press Windows A to launch Action Center. You can also click the taskbar icon in the lower right corner of the screen.

Now click on the slider and adjust the screen brightness as per your requirement.

You have now adjusted the brightness from Action Center.

Method 2: Use keyboard hotkeys

If you use a keyboard with dedicated hotkeys, you can use the same hotkeys to adjust the brightness. This mainly applies to laptops and third-party keyboards.

Look for the brightness icon on your keyboard. Most keyboards place them in the function or Fn key, while third-party keyboards may have dedicated keys at the top.

Just use these keys to adjust the brightness. If you are a laptop user, you will most likely need to use the Fn Brightness key in combination to adjust the brightness. This is because the key will act as a function key unless a dedicated Fn key is used as a modifier to use its alternate function.

If you wish, you can change this behavior on Windows using the Fn Lock feature on most keyboards.

Fn lock is usually activated by Fn Caps Lock or Fn Esc. If you have this feature, you can use these combinations to quickly change the function of the function keys.

However, if your keyboard does not have Fn Lock functionality, you must continue to use the dedicated key combinations on your keyboard to control brightness.

Method 3: Use dedicated monitor controls

If you can't access the brightness slider in Action Center, it's most likely because you're using an external monitor.

Unless your external monitor comes with a dedicated driver or utility, Windows cannot control brightness using built-in utilities.

In this case, you will have to use your monitor's OSD to change and adjust its brightness. Most monitors will use the following terms in their OSD for brightness settings.

• Brightness
• Backlight
• Backlight intensity

##Note: If your monitor has both Brightness and Backlight options, the Backlight will help you adjust the actual brightness of your monitor. Instead, the Brightness option will adjust the Gamma for your 's PC display output.

Here are some common monitor OEMs and their dedicated apps to help you control monitor brightness and more. Use any of the links below depending on the OEM of your monitor.

You can use the OSD and dedicated keys on your monitor, or you can choose a third-party utility to help you. Follow any of the sections below based on your current preferences and requirements.

Tip 1: Use the Dedicated Monitor Key

Most external monitors come with a built-in OSD display that allows you to access the monitor's features and adjust its display output. This OSD can be accessed using a dedicated key on the monitor or its dedicated remote control.

Launch the OSD on your monitor and look for a slider or value named one of the following.

Brightness

• However, if your monitor does not have a built-in OSD or brightness settings, you can use one of the third-party apps mentioned below to adjust the brightness of your monitor. Tip 2: Use a third-party app

We recommend the following apps to adjust brightness for multi-monitor setups. Our top picks are Monitorian and Dimmer. Both apps are suitable for multi-monitor setups, with built-in support for most screens currently available on the market.

Monitorian is our top choice because the tool can connect directly to your monitor's backlight and adjust its brightness. On the other hand, if a compatible driver cannot be found, the dimmer will resort to adjusting brightness and gamma to increase or decrease the brightness. Use the links below to download and test the apps and find the one that works best for your current setup.
