Automatic screen dimming is a useful computer feature that helps you adjust the brightness depending on the lighting level indoors or outdoors without any human intervention. Sometimes this is very annoying, so users are looking for instructions on how to disable auto-brightness in Windows 10 once and for all, so that turning the lights on and off or moving the laptop screen does not in any way affect the set brightness level of the monitor. It is necessary to take a closer look at what to do if the screen changes brightness automatically (Windows 10) and how to deal with it.
Why doesn't the brightness change on the computer?
If the brightness does not change with hot keys (for example, fn+F5 or fn+F6), but it can be changed in the power settings, then most likely your laptop does not have a special application installed that activates special hot keys specifically for your laptop model.

How to remove screen dimming in Windows 10
As has already become clear, some computers running Windows can automatically configure and adjust the brightness setting of the screen or monitor. This will depend on the specific lighting conditions in the room. In complete darkness, the display can glow more dimly, and when exposed to bright light, it will automatically increase the brightness. Perhaps the function will work the other way around: when the lighting brightness increases, the screen will become brighter, and when it decreases, it will become dim.

To find out if your PC or laptop supports this function, you need to:
- Go to the “Options” section (“Win + I”).
- Find the “System” section and the “Screen” subsection.
- In the “Brightness and Color” section, check for the “Automatically change brightness when lighting changes” setting.
Important! If the parameter exists, then you simply need to disable it by applying and saving the settings. Sometimes you may need to restart the operating system and the entire computer for them to take effect.
You can change the auto-brightness setting in the “Control Panel”

Problem with Intel video cards
If your laptop has a built-in Intel 4000/530 or other video adapter, and the first method did not help, then do the following. Right-click on the desktop and select “Graphics characteristics”
The Intel HD Graphics Driver Control Panel will open. If this is not the case, then write “intel” in the search bar of the Start menu and select “Intel(R) Graphics and Media” from the results.
In the driver panel, select “Power Options”:
Next, turn off the display energy saving technology and set it to maximum quality:
The second option is to disable “Extended battery life for gaming applications”. Surprisingly, this can affect the floating brightness on the desktop.
Check the list of startup programs
If your Windows 10 screen dims a few seconds after your computer boots, the startup program could be the culprit. Your system loads a lot of programs at startup, and it's worth checking this list of programs to look for any suspicious items.
- Open the Start menu, search for Settings, and select Settings from the search results.
- Select Applications in the Settings window.
- From the left sidebar, select Launch.
- On the right, all programs with the switch enabled can start when your computer boots.
- Disable all or only suspicious programs in this list. A suspicious program is basically a program that you recently installed before the screen problem occurred.
- Restart your computer and see if the problem goes away.
