This article describes a by-design behavior that computer monitor turns off after 1 minute when the computer is locked and provides a solution to solve this issue.
Applies to: Windows 8, Windows 8.1, Windows 10, Windows 11
Original KB number: 2835052
Consider the following scenario:
In this scenario, you may observe that the PC monitor turns off after 1 minute. Changing the setting "Choose when to turn off the display" under Power Options in Control Panel does not change this behavior. This setting can be used to adjust the display timeout used when a user is logged in and idle but does not affect the timeout used when the PC is locked.
This behavior is by design in Windows. By default, when the console is locked, Windows waits for 60 seconds of inactivity before powering off the display. This setting is not configurable using the Windows user interface by default.
Using the PowerCfg.exe utility, you can configure the display timeout used when the PC is in an unlocked state as well as when it is at a locked screen. From an administrative command prompt, the following commands can be used to control the display timeout:
powercfg.exe /setacvalueindex SCHEME_CURRENT SUB_VIDEO VIDEOIDLE \<time in seconds>
powercfg.exe /setacvalueindex SCHEME_CURRENT SUB_VIDEO VIDEOCONLOCK \<time in seconds>
powercfg.exe /setactive SCHEME_CURRENT
The VIDEOIDLE timeout is used when the PC is unlocked and the VIDEOCONLOCK timeout is used when the PC is at a locked screen.
Note
Using Powercfg commands to set the timeout only affects the current power scheme where the system is plugged in and using AC power. To set the timeouts used when on DC (battery) power, use the /setdcvalueindex switch instead of the /setacvalueindex switch.
In Windows 10 and Windows 11, you can expose the Console Lock Display Off Timeout setting under Change Plan Settings. From an administrative command prompt, the following commands can be used to expose the control.
powercfg.exe -attributes SUB_VIDEO 8EC4B3A5-6868-48c2-BE75-4F3044BE88A7 -ATTRIB_HIDE
To hide the option, run the following command:
powercfg.exe -attributes SUB_VIDEO 8EC4B3A5-6868-48c2-BE75-4F3044BE88A7 +ATTRIB_HIDE`
