On a MacBook Air (M2, 2022), go to System Settings >> Lock Screen and check the appropriate setting:
“Turn display off on battery when inactive” or “Turn display off on power adapter when inactive.”
Apple provides separate settings for these two situations. (Apple Support)
If you are specifically trying to make the display turn off, the Lock Screen setting is the relevant one.
The separate “Prevent automatic sleeping on power adapter when the display is off” setting in System Settings >> Battery >> Options concerns the Mac going to sleep after the display has turned off; it does not set the display-off timeout itself.
If the display still does not turn off at the selected time, tell me whether you are testing on battery or while connected to power, and what happens when the selected time has elapsed. That will determine the appropriate next step.

To fix the issue where your MacBook's auto-lock or display-off settings refuse to change or apply, check for MDM configuration profiles, third-party apps, or system conflicts
