Lock Screen Dims (Brightness Auto Reduce at Lock Screen)

Hi,

Since you're having an issue with the brightness of your Lock Screen, we suggest uninstalling the display adapter from the Device Manager. Just follow the steps below:

• Press Windows key + X.
• Select Device Manager.
• Locate and expand Display adapter.
• Right-click on the display device and click uninstall.

Note: Please restart your computer after performing the steps above.

If the issue persists, download and install latest display driver from the computer manufacturer's website.

Please update us with the status. We will be glad to assist you.

 

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! -
