In Windows 10, how do I prevent my displays from turning off shortly after locking my screen?
Power savings nor display life are an issue for my situation.
Reason: I have an external dock that causes all my windows to move to my primary display after the displays are turned off.
This how-to assumes you are comfortable with editing the registry. Serious damage can be done if you make a mistake!
- enable "Console lock display off timeout" in the Advanced Power Settings via the registry:
- set "Attributes (type DWORD)" to 2
- (to hide, set Attributes back to 1)
- open advanced power options (or close then reopen, if it was already open before the registry change)
- change timeout to desired value (example screenshot below):
- This was tested to work in Windows 10 Pro.
- Changing this setting is strongly discouraged in situations where power saving or monitor life are important.
- This only works for lock screens while a user is signed in.
