Screen Shut Off Problem With New Monitor ?

Hi Folks,
In my 80's now, so please bear with me a bit.

Have a new LG 27" 4K Monitor, but pretty sure that this is a W10 issue. (but maybe not ?)

I want the screen to shut off after 5 minutes.
So, I have it set to that.

But, it always comes back on by itself.

Absolutely no vibration or jiggling of the keyboard, etc. that might account for it.

Also get a msg related the it is going to the Power Saving/Setting when it does.

And this on-off cycle seems to repeat every 5 minutes.
Can't imagine anything I've done incorrectly, or what might be wrong.

Similar problem if I use in conjunction with the Sleep Mode, or just the Sleep Mode.

Anyone know anything about this kind of "problem" ? Sure is annoying.

It seems that the Screen Shut Off, and Also the Sleep modes, and the Power profiles
don't work the way they should. But maybe it's just me.

Might someone who really understands these modes walk me thru Exactly what each is supposed to do, and any
interactions between any of the three of them.

Would be most appreciative.

Thanks,
Bob

When the PC sends the monitor to sleep, what it does is cut off the signal to the monitor. (It doesn't send a command.) The monitor detects the signal loss, and goes into power saving mode. You should get messages to that effect. I don't recall the exact messages on my LG monitor. It sounds like you're seeing the normal things.

If the monitor is waking up, there imay be some process on the PC that is doing that. Perhaps a process that isn't part of Windows. I can't guess what it could be. Antivirus software, backup software?
