Windows 10: Night light and brightness not working

Hi I'm Aanchal pandey and I have a lenovo laptop with windows 11 installed, my display doesn't seem to be functioning properly. The brightness and night light are not changing everything else seems to be working so far, can I get a suggestion on how to fix this issue. Regards

:)

 

Night Light Settings

Separately from the Night Light, is the brightness options also disabled? If so, I might recommend these steps to make it work again:

1) Right-click Start button, choose Device Manager

2) Find the "monitors" section in the list and expand it

3) Right-click and uninstall every item listed under the monitors section

….. note: don't accidentally go to the "display adapter section", leave that one untouched.

4) Click the "scan for hardware" button on the toolbar up top (the icon with the magnifying glass inside it)

5) Try brightness and night light settings again

Broken brightness setting and Night Light

Hello,

Since scheduling night light I'm unable to change screen brightness setting. Night light strength adjustment also not working even in night light schedule "off" time. Turning off the schedule switch altogether solves night mode strength lock but global screen
brightness still locked, ie the brightness slider moves but screen brightness doesn't change whatsoever ie, broken.

I've never installed flux etc, only the native night mode on the new surface 7 with up to date windows. Brightness slider worked as expected before scheduling night mode.

When night light schedule is turned off via switch in settings global brightness slider is still ineffective and broken, it slides to no effect.

Many thanks for reading.
