Windows 10: Unable to change Display Resolution or Brightness level in Windows 11

I am using Windows 11I can't change my Display Resolution, the entire option is greyed out and refresh rate has become fixed.As described, when I right click on the screen and choose "Display settings" to open the system window, the "Display Resolution" area where you can adjust the resolution for your monitor is fixed at "3840x2160Recommended", and I can't change it to any other resolution, the whole selector is greyed out.

Unable to set brightness level for Plugged in and on battery

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to set brightness level for plugged in and on battery.



I would like to inform you that the brightness slider to adjust brightness separately was removed from Windows 10 starting from the build version 1903. The screen brightness can be adjusted using the slider from the Notification center.



Ideally, the brightness slider will allow a user to adjust the display brightness, and that brightness will be remembered as the preferred brightness whether the laptop is on battery or connected to a charger.



However, as you have mentioned that after an update the feature is not working, we would like to know the update that was installed recently. To check go to
Start >> Settings >> Update & Security >> Windows Update >> View update history.



We would also like to know the build version of Windows installed on the computer currently. To check type: winver in the
search bar on the Taskbar and hit Enter.



Meanwhile, I would suggest you to try updating the display drivers and check if that helps. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select
   Device Manager.
   
2. Expand Display adapters.
   
3. Right click on the display
   device and select Update Driver.
   

Article for reference:
Update drivers in Windows 10.

Let us know how it goes.

Laptop brightness display level

After the latest Windows update, I cannot change the display brightness level(HP laptop) which is set on high. Please advise. I have tried both the brightness level keyboard key, and the Windows setting option.

 

Display resolution keeps changing

Hi Rick,

It might be caused by a faulty driver that's why your display resolution keeps changing. We
suggest that you uninstall and reinstall the display driver, see steps below:

• Press Windows key + X and click on
  Device Manager.
• For graphics cards, expand the Display adapters category, right click your graphics card and select Uninstall.
• Restart your PC and Windows will attempt to reinstall the driver.

Let us know if you have any other questions.
