Can't turn off adaptive brightness

[Meowi]

Hi, I am running windows 11 on my HP Spectre and find the brightness is always changing making the screen hard to read at certain times. I have followed the steps on another feed and checked to see if there was a toggle under control panel >advanced power settings, however it is not showing there. I also checked to see if there was a BIOS update required which there is not. How can I turn off the adaptive brightness? Thank you.

Hi @Meowi,

Welcome to the HP Support Community. 

I'd like to help!

Go to the Start menu and open the Control Panel

2. In the Control Panel, go to Power Options

3. After the Power Options window pops up, click on Change Plan Settings to look at your current power plan

4. Choose the option to Change advanced power settings located at the bottom of the window. This will open up the Advanced Power Options window

5. Scroll down to the Display option. Expand it to show the Adaptive Brightness option

6. Choose to turn on or turn off this feature for both when it’s on battery power and when the computer is plugged in

7.Save the settings through clicking Apply and then OK

If you don’t find an Adaptive Display setting, your device might not have a built-in ambient light sensor.

8. If you followed the instructions but the adaptive brightness didn’t change your auto-brightness setting, you’ll need to turn off the Sensor Monitoring service by pressing Win + R and typing services.msc. Then press Enter

9. In the services window, click on the Sensor Monitoring Service which will lead to the service settings window

10. Click Stop and select Disabled from the drop-down menu found next to the Startup type

11. Save changes by clicking OK

Hope this helps! Keep me posted for further assistance.

Hello, the adaptive brightness setting doesn't appear on my computer. What would be the reason the computer is always adjusting the brightness if this is not an option on my laptop?
