The display brightness and contrast of your Windows computer can make a big difference in how comfortable the screen feels. If the screen is too bright, it may feel uncomfortable in a dark room. If it is too dim, text, photos, and videos can become difficult to see. Adjusting the contrast can also help make text and other elements easier to distinguish.

Windows provides several ways to adjust brightness, including Quick Settings, Windows Settings, keyboard shortcuts, and laptop-specific function keys. 

However, the exact method can vary depending on whether you are using a laptop, desktop monitor, or external display.

This guide explains how to adjust brightness and contrast on Windows 11 and Windows 10, including the keyboard shortcuts commonly available on different laptops.

Adjusting Display Brightness and Contrast on Windows

To adjust display brightness on Windows 11 or Windows 10, use the brightness slider in Quick Settings or go to Settings > System > Display. 

On many laptops, you can also use the brightness function keys, usually marked with a sun icon. Windows does not provide a universal keyboard shortcut for directly changing screen contrast, but contrast can be adjusted through Accessibility settings, graphics software, or the controls built into an external monitor.

Before changing the settings, it is useful to understand the difference between brightness and contrast. Brightness controls how light or dark the entire display appears, while contrast controls the difference between lighter and darker areas of the image.

1: Check Your Current Display Brightness

Start by checking how bright or dark your screen currently appears. This is especially useful if you are troubleshooting a display that suddenly looks too dark or too bright.

On Windows 11, press Windows + A to open Quick Settings. Look for the brightness slider, which usually has a sun icon. Drag the slider toward the left to reduce brightness or toward the right to increase it.

On Windows 10, press Windows + A to open the Action Center. Depending on your computer and Windows version, you may see a brightness control at the bottom of the panel.

If you cannot find a brightness slider, do not worry. Your computer may use a hardware brightness control, an external monitor, or a graphics driver that does not expose the brightness control through Windows.

2: Adjust Brightness From Windows Settings

You can also change brightness through Windows Settings. This method is particularly useful when you want more control over your display.

On Windows 11, press Windows + I to open Settings. Select System, then select Display. Under the Brightness & color section, locate the brightness control.

Move the slider until the screen reaches a comfortable level. If your computer has more than one display, make sure you select the display you want to adjust before changing its settings.

On Windows 10, open Settings > System > Display. Look for the Brightness and color section and adjust the brightness slider.

This method is useful for beginners because Windows clearly identifies the setting instead of requiring you to remember a keyboard shortcut.

3: Use the Laptop Brightness Keyboard Shortcuts

Most laptops provide dedicated brightness keyboard shortcuts. Look at the top row of your keyboard, particularly the F1 through F12 keys. Look for a symbol resembling a sun.

One key normally decreases brightness, while another increases it. On some laptops, you can press the brightness key directly. On others, you need to hold Fn while pressing the appropriate function key.

For example, a laptop may use Fn + F5 to decrease brightness and Fn + F6 to increase brightness. However, these keys are not universal. The exact combination depends on the laptop manufacturer and model.

If pressing the key does nothing, try holding Fn while pressing the brightness key. You may also need to check whether your laptop’s function-key mode has been changed.

4: Try the Windows Mobility Center

Windows also provides the Windows Mobility Center, particularly on laptops.

Press Windows + X and look for Mobility Center. If available, open it and locate the Display brightness control.

You can adjust the brightness using the slider provided there. This can be useful when the normal brightness control is difficult to find.

The Windows Mobility Center may not be available or may have different options on every Windows edition, so use the Settings method if you cannot find it.

5: Adjust Automatic Brightness Settings

Some laptops automatically change screen brightness based on lighting conditions, battery settings, or displayed content.

On Windows 11, go to Settings > System > Display and expand the available brightness-related options. Depending on your hardware, you may see options related to automatically adjusting brightness or changing brightness based on content.

If your screen keeps becoming brighter or darker without you changing anything, check these options.

On supported devices, disabling automatic brightness adjustments can give you more consistent screen brightness.

6: Adjust Contrast Through Windows Accessibility Settings

Brightness and contrast are separate controls. Windows does not normally provide a simple universal contrast slider alongside the standard brightness control.

If you need stronger visual separation between text, buttons, backgrounds, and other interface elements, Windows provides Contrast themes.

On Windows 11, open Settings > Accessibility > Contrast themes. Select a theme that provides the type of contrast you need and apply it.

On Windows 10, open Settings > Ease of Access > High contrast. From there, you can enable and configure high-contrast options.

This setting changes the appearance of Windows rather than simply increasing the physical contrast of your monitor.

7: Adjust Contrast Using Your Monitor Controls

If you are using a desktop computer with an external monitor, Windows may not provide a direct brightness or contrast control.

In this situation, use the physical buttons or joystick on the monitor. Press the monitor’s Menu button and look for options such as Brightness, Contrast, Picture, or Image.

Increase or decrease brightness first. Then adjust contrast until dark areas remain visible while bright areas do not look washed out.

The exact menu names depend on the monitor manufacturer.

Check Your Graphics Driver if the Brightness Control is Missing

If the brightness control is missing or does not work, the problem may be related to your display or graphics driver.

Press Windows + X and select Device Manager. Expand Display adapters and check the graphics hardware listed there.

You can also check Windows Update for available driver updates. On some computers, especially laptops, the manufacturer’s graphics driver is required for brightness controls to work correctly.

If brightness stopped working after a Windows update or driver change, checking the graphics driver is particularly worthwhile.

Adjusting Display Brightness and Contrast on Various Windows Laptops With Keyboard Shortcuts

Different laptop manufacturers use different keyboard combinations. There is no single brightness shortcut that works on every Windows laptop.

Dell Laptops

Many Dell laptops use function keys with sun symbols for brightness control. Depending on the model, you may need to press the brightness key together with Fn.

Look for the keys marked with a sun icon and try the appropriate key. If the function keys behave differently from expected, check whether Fn Lock is enabled.

HP Laptops

Many HP laptops place brightness controls on the function-key row. Look for the keys showing a sun symbol.

You may need to press Fn together with the corresponding brightness key. The exact F-key number varies by HP model.

Lenovo Laptops

On many Lenovo laptops, brightness controls are assigned to function keys with sun symbols. Press the appropriate key, or use Fn + the brightness key if required.

Some Lenovo keyboards also allow you to change how the function keys behave through BIOS or Lenovo software.

ASUS Laptops

Many ASUS laptops provide brightness controls on the function keys. Look for the sun icons and press the corresponding key.

If the shortcut does not work, try holding Fn while pressing it. ASUS laptop models can use different function-key arrangements.

Acer Laptops

Acer laptops commonly use function keys for brightness. Look for the brightness symbols on the keyboard and use the corresponding key, with Fn if necessary.

Microsoft Surface Devices

On supported Microsoft Surface devices, brightness can generally be controlled through the keyboard’s dedicated brightness controls or Windows Quick Settings, depending on the keyboard or Type Cover being used.

If a keyboard shortcut is unavailable, Windows + A provides a simple alternative on Windows 11.

Important Keyboard Shortcut Reminder

The most useful universal Windows shortcut for accessing display controls is Windows + A, which opens Quick Settings on Windows 11. However, the actual brightness function-key shortcut is manufacturer-specific.

There is also no universal Windows keyboard shortcut, such as Ctrl + A, that directly changes monitor contrast. For contrast adjustments, use Windows Accessibility settings, graphics software, or the monitor’s own controls.
