How to Adjust Screen Brightness in Windows 10
Proper brightness not only improves visual comfort, but also effectively reduces eye fatigue, especially in the case of prolonged computer use. This article will focus on how to adjust the brightness of the display in Windows operating system.
Step 1: Adjusting Brightness Through Windows
In the Windows operating system, adjusting the brightness of the screen is very simple and can usually be accomplished through the system settings, shortcut keys and the control panel of the external monitor. Below is a detailed description of several common methods.
1. Shortcut keys to adjust the brightness
For laptop users, the easiest way to adjust the brightness is through the function keys on the keyboard. These shortcut keys are usually located in the upper row of the keyboard, especially the F1 to F12 keys. Many laptops have dedicated brightness adjustment buttons, usually represented by a sun icon. Users can quickly adjust the brightness of the screen by simply holding down the "Fn" key and then pressing the keys to increase or decrease the brightness at the same time. For example, the F1 key may decrease the brightness, while the F2 key is used to increase the brightness.
2. Adjusting brightness through system settings
In Windows 10 and later versions, users can adjust the brightness through system settings. The steps are as follows:
Click the "Start" menu in the lower left corner and enter "Settings".
In the Settings interface, select "System".
Enter the "Display" tab, you will see the "Brightness and Color" section. There is a slider that allows users to increase or decrease the screen brightness by dragging the slider.
This method works for built-in monitors or external monitors that support brightness adjustment. It should be noted that the brightness adjustment of some external monitors for desktop computers cannot be controlled by the operating system settings, and you need to use the physical buttons or menus on the monitor itself to make adjustments.
3. Automatic Brightness Adjustment
Many modern laptops are equipped with an ambient light sensor that automatically adjusts the screen brightness according to the ambient light. Users can enable this feature in the "Display Settings". Once enabled, the computer screen will automatically reduce its brightness when the ambient light is low, and increase its brightness in bright environments.
Step 2: Updating the Display Driver
Sometimes, when adjusting the brightness of the display, users may find that the screen brightness cannot be adjusted, or the response is slow when adjusting. In this case, the problem may be related to the display driver. The driver is the bridge between the operating system and the hardware device, and a wrong or outdated display driver may cause the brightness adjustment function to fail.
To ensure the best display results, you need to check and update your graphics card driver regularly. We can install "Driver Sentry", which can help to automatically detect and install the drivers to ensure that the graphics card drivers in your system are up to date and avoid compatibility issues.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
After the scan, identify the display driver in the results list and click "Upgrade".
Restart your computer after updating the drivers to ensure the changes take effect.
The above is the way to adjust screen brightness in Windows 10, hope it helps you. If you encounter problems with your network card, graphics card, Bluetooth, sound card and other drivers, you can download "Driver Sentry" to detect and repair them.
