Monitor doesn't turn off

Ok, I have it set up just like I did with Win7. Screen saver set for 10 minutes, monitor power off set for 15 minutes. The problem is, the monitor doesn't turn off! To be more accurate, it DOES turn off at the 15 minute mark, for about 1 minute. Then it turns back on and the lock screen shows. Then after 1 minute, the display fades out to black, but the monitor itself is still on.

I've dug through every possible thing trying to fix this, even disabling the lock screen, but nothing helps. I've never been able to get the monitor to turn off for more than 1 minute.

You might have ticked the "Put computer to sleep after" ten minutes...



Try finding the "Choose when to turn off the Display" in search.

Put it to ten minutes (I assume you already did this, but just in case, I wrote it out)



I have a dumb bug in my desktop that causes it to come out of sleep randomly at crazy hours of the night or day.

Even if I put it back to sleep, after a minute it wakes up again.

I'm guessing it has something to do with windows update, but I'm not sure.


But This might be a different problem... If there's a running program on your pc then it might be what's causing it to wake up.

Also wake on LAN could be a problem.

Ok, I found something weird. If I set the screensaver to none and uncheck the ask for password when waking up option in there, THEN the monitor will turn off as expected and stay off. So it seems to be a bug with the Win8 lock screen.

Glad you found a temporary fix.

Play around with it, and maybe you'll fix it.:thumb:

Ok, the monitor will not stay off if Win8 is on the lock screen. It will turn off, then turn back on after 1 minute. If it's not on the lock screen, the monitor turns off like it's supposed to and stays off.

Ok, I've been playing around with this, and the "on resume, display logon screen" is the culprit. If this is checked, the monitor will not ever turn off. Looks like a bug in Windows itself. If this option is checked and you lock the computer, after 1 minute the monitor turns off for about 10 seconds and then turns back on with a black screen. If it's not checked, then you can lock the computer and the monitor will turn off after a minute.

No, if this was a bug in Windows itself it would affect everyone. But it doesn't, as my monitors turn off just fine and I have on resume turned on. What seems to be happening is that your computer is resuming after going into sleep. There is probably something that is preventing it from going into sleep, or causing it to wake.. probably driver related.
