Brightness setting in Windows 10 Enterprise 22

Question

Brightness setting in Windows 10 Enterprise 22

JayHenry 0

We have an issue where brightness changes have no effect under settings in Windows.

Whether night light is on or off the slider has zero effect on the screen brightness.

We are using Win10 Enterprise 22H2 and this feature does not work for any computer in our organization.

Our Sys Admin isn't sure what could be disabled that would allow for the feature to be available but nonfunctional.

This has not worked for years, and I want to find a solution.

Many laptops have function keys (e.g., F2 and F3) that allow you to adjust brightness. These keys often require you to press and hold the "Fn" key simultaneously. Make sure you are using the correct function keys to adjust brightness.

Make sure the "Enable adaptive brightness" setting is turned off under Power Settings.

Right-click on the desktop and select "Display settings."
Scroll down to the "Multiple displays" section and select "Disconnect this display."
Once you've disconnected the display, try adjusting the brightness again.

Update Graphic card driver.

Run the System File Checker utility to check for and repair any corrupted or missing system files that may be causing the issue.

Open a Command Prompt as an administrator.
Type the following command and press Enter: sfc /scannow

The computers experiencing this are All-in-ones and SFF towers for an organization. There are no function keys applicable.

I do not see an adaptive brightness setting under settings or in the power settings in the control panel. This option could be restricted by Sys Admin

The "disconnect this display" option does not work. I can select it but then nothing changes on any of the displays. If I select a display and turn it off then leave out of that portion, when I go back the radio button is disabled again. As in Windows is turning it back off.

Graphic drivers are drivers provided by Dell for AIO and are up to date.

I can try running SFC, however this problem is affecting hundreds of computers. I believe it is something our Sys Admin disabled in setup of all these devices, but we are unsure what would disable these display settings from being accessible.

We also tested to see if moving the computer into a different OU with zero GPOs applied would resolve the issue. However, the issue was still prevalent. We have tested using different computers inside the organization and the issue is still there.
