In this tutorial I will guide you how to adjust the brightness of the computer screen.

For laptops, it’s too simple because it is already built into the keyboard. On a desktop computer (Desktop), the adjustment will be a bit difficult for newbies.

Okay, it’s okay! In this tutorial I will share with you all the simplest way to change the brightness and darkness of the PC and Laptop screen so that you have many methods and options for successful implementation.

I. Guide to adjust laptop screen brightness

As I said above, for the Laptop screen, there are many ways. And the way we often use the most and also the fastest is to use keyboard shortcuts.

#first. Use keyboard shortcuts


Usually on the keyboard there will be 2 keys similar to the image above to help you increase or decrease the screen brightness. Each laptop line is designed differently, so these 2 keys are not fixed in any position.

For example, as shown above, you can see it is located with the key F1 and F2. But many machines are in other positions, for example F3, F3 or F9, F10 or also the keys F11, F11….

Therefore, please pay attention to see where the two icons above (or similar to above) are located on the keyboard to use.

=> How to use: Use key combinations Fn with the key symbol a sun (light).

Fixed an issue where the screen brightness could not be adjusted

There will be a few cases when you use this shortcut faulty, and of course you will not be able to increase or decrease the screen brightness. This error I determined is due to the driver of the video card is old or missing. The simple workaround is to install more video card drivers on the computer.

#2. Adjust screen brightness through Windows Mobility Center

With the Windows Mobility Center tool built into the computer, you can not only adjust the brightness of the screen, but you can also adjust the sound, choose the type of Battery to use, …

# 4. Increase or decrease the brightness of the Windows 10 screen

If you are using Windows 10 operating system, this is even simpler. You can adjust the screen light extremely quickly.

Unlike laptops, it’s not that simple. For desktops, the screen brightness increase or decrease is a bit different.

#first. Use F.lux software (recommended)


According to my personal assessment, this is the best way. Using F.lux free software not only adjusts the screen brightness easily, it also protects your eyes when using at night.
