Here’s How to Manually Change Your Windows 11 Display Brightness

Why Change Screen Brightness?

Comfortable eyes depend heavily on correct screen brightness. Excessive brightness feels harsh in dark surroundings. Dim displays challenge visibility and cause eye strain. Finding the right balance prevents discomfort.

What Happens When You Change Brightness?

Moving the brightness slider alters the amount of light the screen emits. Increasing brightness forces the screen to output more light. Dimming reduces this output. Room lighting and personal preference dictate the ideal setting.

Quick Way: Adjust Brightness from the Taskbar

Laptops benefit most from this taskbar shortcut.

Step 1Open Quick Settings

Opening Quick Settings starts the adjustment process. Click the icons for Wi-Fi 📶, sound, or battery near the clock on the taskbar 🖥️. This panel gives swift access to frequently used controls.

Administrator privileges (special permissions required to make system-wide changes) are necessary. Standard user accounts require these permissions to adjust Windows 11 display brightness.

Step 2Find the Brightness Slider

Locate the brightness slider after opening Quick Settings. A sun icon typically sits nearby. Alternative methods exist if this slider remains hidden.

Desktop computers using external monitors often omit the Windows 11 display brightness slider. Users missing this slider must open the Settings app instead.

Step 3Adjust the Brightness

Click and drag the circular control on the slider. Moving it left dims the screen; moving it right brightens it. Release the mouse button when the display looks right.

Detailed Way: Adjust Brightness in Windows Settings

Taskbar sliders that remain missing require the Windows Settings app for display adjustments.

Step 1Open Windows Settings

Click the Start button (the Windows logo) on the taskbar. Select the gear icon for Settings. Pressing Windows key + I simultaneously on the keyboard opens this menu faster.

Step 2Go to Display Settings

Choose System from the left-hand menu within the Settings app. Click on Display next.

Step 3Find the Brightness Slider

Missing Quick Settings sliders appear within the main Windows 11 Settings app. Navigating to the 'Display' page reveals another location for managing screen brightness.

Desktop computers connected to separate external monitors usually lack a brightness slider in this menu. External monitors feature physical buttons for brightness control. Use the buttons built directly into the monitor.

Step 4Adjust the Brightness

Dragging the display slider left or right changes the screen illumination level. Moving it one direction dims the screen, while moving it the opposite direction increases brightness. This lets you set preferred viewing levels.

Summary

Windows 11 screen brightness adjusts through the Quick Settings panel on the taskbar or the Windows Settings app. Controlling display illumination reduces eye strain and improves viewing comfort in any lighting.
