Monitor will not sleep while computer is locked

Try turning off the screen saver. No real need for screen savers anymore with the option to turn the monitor off.

Alright, I tested that out and it did not work.

Did you Reboot the system after making the change?

I've recently ran into this problem on my computer. My monitor will not sleep while the computer is locked. If I just let it sit, the screen saver will appear, then the monitor will sleep. However, once the computer is locked, the monitor will not sleep.

The monitor auto sleeping was working perfectly fine last week.

Edit: What I've done/tried:
Triple checked monitor settings/power options
Reset to defaults, then set the monitor to sleep at 10 minutes
Changed to a new theme
Enabled monitor sleep GPO
Restarted multiple times
Disabled screen saver
My monitor has no sleep settings

Then apparently it's working like it should? What do you mean when you say the "computer is locked"? Does that mean a BSOD, turned off or what? The screen saver and power options will only work if Windows is active. And if your monitor doesn't have a power saver option (sleep), it will just sit there waiting for a signal from the PC.

He means when you press the Windows Key + the L (l) key the computer goes into Lock Mode, IE the computer is locked.

I do that with my Work notebook computer all the time and with my home desktop if I am going out of the house for a time and don't want to shut down or put it to sleep.

With either system once in the Locked mode the monitor turns off at the time specified in the Power Options settings.

Sometimes monitors will have their own settings. I was just saying that my model doesn't have any settings, but it does have the "power save" a.k.a. sleep function.

I did not reboot my computer, that really shouldn't have much of an effect on it after disabling my screen saver.

Well you don't know that unless you try it.

Alright, I have restarted. Screen saver is disabled, monitor sleep time set to 2 minutes. It did not sleep.

I don't know what's going on here. I really don't want to reinstall Windows because of this.

What have you changed on your system since last week. Something is running in the background that is causing the system to think it needs the monitor on.
