Windows 10: My laptop display was so bright even the brightness control is already in 0. How can I fix...

I just recently update my laptop in Windows 11. Before the update everything is fine but when it's finished my display was bright. I try to lower it but it has nothing done. I already restarted it a few times but it's still the same. Update the monitor and display adapters in device manager it's still no use. What do I need to do to lower the brightness?

Display brightness control cannot be found

I am using Windows 10 Pro 2004 on a Dell 270S mini-tower PC. Neither Windows 10 nor the Intel driver software provide a brightness control. The issue was also with Windows 10 1909. I have a hunch that Microsoft and Intel each thought that the brightness control would be provided by the other. I simply cannot find it.

The display adaptor device is only described as 'HD Graphics' using Intel driver 10.18.10.5059 dated 16 June 2018.
The display screen is a Dell P2212H(Analog).

If anyone has any suggestions where to look for a brightness control, apart from the one on the display monitor control panel, I would be delighted to know about it.

 

Unable to Change Screen Brightness of Laptop


So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
- Reinstalling Display Drivers
- Rolling Back Display Drivers
- Reset Settings on UWT4
- Power and Battery Settings
(UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -

 

Can not control the laptop brightness

Hi Dinh,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently.

I would appreciate if you can provide us the following information to help us understand the issue better.

What happens when you try to change the screen's brightness?

For a majority of laptops, there isn't a control for setting the contrast. However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness
or increase brightness.

I suggest you to uninstall the display driver from your computer and then install in Compatibility mode.

To uninstall the driver follow the steps given below.

• 
  Press Windows key + X and select
  Device Manager.
  
• 
  Search for Display Adapter
  and expand it.
  
• 
  Right click on the Display Adapter
  and select Uninstall.
  
• 
  Do not restart your computer.
  

Once you have successfully uninstalled the driver, please install the driver in compatibility mode following the steps given below.
