screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

Display Brightness with Win 11 Randomly Drops to 20%

I recently installed Windows 11. Since then the display brightness on my Alienware m17 R3 keeps randomly dropping to 20%. Sometimes it will return to normal automatically, other times I have to go into settings and adjust the brightness slider manually. I've been using PCs for about 40 years and am pretty good at solving problems like this, but this one has me stumped. All settings related to display brightness are where they should be so as to not randomly dim the screen. I searched the web for info in case there was a setting I was missing, but I'd covered them all. This problem occurs both with and without apps open. Any suggestions appreciated.
