Change Lock Screen Display Off Timeout in Windows 10  

Brink said:

Does having it set with this prevent your display from turning off automatically?

NO. Displays still goes black after several minutes as i said before.

This behavior is strange for me too.

Hello, sorry for bumping this rather old thread, but I just wanted to give my "I have also this problem" and give a cent or two:

As tsuak posted in the image in #16, the "Lock Screen Display Off Timeout" option is not present in Power Options window, so unable to set it via option 1.


If I go with option two, the command line option, I start with getting list of schemes with
powercfg /list
Copying the GUID and querying the scheme with
powercfg /query <Scheme GUID>
and scrolling down to Display, the "Lock Screen Display Off Timeout" is not present here either.

If I run your command anyway:
powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_VIDEO VIDEOCONLOCK 3600
and then query the scheme afterwards, the option still don't appear.

So I guess Windows Updates has made this void - at least for my Windows 10 Pro N 64bit (Version 1803, Build 17134.285)

Yeay, thanks!



A bit funny, the value I set yesterday via CLI was actually saved, even though I couldn't see it in the query. Must have been because the feature itself was disabled (not just hidden), as it was still turning off the displays after one minute (AC).

I just tried locking and the displays stays turned on after 2 minutes. GREAT! Thanks!

Hello Shawn

I haven't been able to find a timeout which would cause a newly-powered-on PC to display the 'splash screen' (which appears to be the same as the Lock Screen) for just a set period of time before going to black, rather than what seems to be 'permanently'.

Have you come across any registry settings which could implement my heart's desire?

Thanks!
