XPS 8960, Waking During Sleep, Continued
I very much appreciated the discussion in XPS 8960, waking during sleep, turning on the GeForce 4060 Ti light and waking monitor as I have noticed the same behavior with my own XPS 8960. To wit: my monitor wakes up just long enough for it to display that there is no signal on the DisplayPort and then it goes back to sleep, and it does this several times throughout the day and night.
This part of the discussion caught my eye: "Using Sleep on a desktop with added storage peripherals will always lead to issues".
As you know, my XPS 8960 shipped with Modern Standby (which I have not attempted to change) and I have in fact attached a Toshiba Canvio external hard drive to the desktop, so I can run backups overnight. (The Toshiba has no apps - it's just a drive.) And I have in fact set my (Dell P2719H) monitor to sleep after 20 minutes.
Why will this setup 'always lead to issues' and what kind of issues are we talking about, specifically?
Being able to run backups overnight is important to me, and if that means my monitor wakes up occasionally, then so be it. No harm is done. Nevertheless, the techie in me would like to prevent my monitor from waking, if possible, or at least to understand why it wakes.
Many thanks for your help.

Did you try running the commands I posted in that other thread?
What happens if you use hibernation instead of sleep? Will the backup still run properly without waking the monitor?
If your mouse has an on/off switch, try turning it off at night when it's going to run backups.

@RoHe
With respect to the commands you referenced:
powercfg -waketimers only shows the waketimers for my backup jobs
powercfg -lastwake didn't return anything useful
I also thought about random mouse shaking/vibration waking up the monitor, but that wasn't the case. Besides, I need to give my Logitech mouse pronounced movement before it brings the monitor out of sleep. And WoL is not enabled.
It wasn't you who said that "using Sleep on a desktop with added storage peripherals will always lead to issues". I wish I knew what that meant.
If it matters: I'm not putting my 8960 to sleep after 20 minutes - I'm powering off the monitor after 20 minutes. I actually don't put my desktop computers to sleep, ever.

Sorry, I don't understand...
If your PC isn't ever sleeping and you're just "powering off the monitor after 20 minutes", why does monitor say there's no DP signal when it wakes? Shouldn't it see a DP signal immediately when it wakes?
Is there a background process scheduled to run when PC is sleeping, aside from your backups that might trigger the monitor?
What about using the monitor's on/off switch to turn it off instead of letting Windows do that? Can't walk something that isn't turned on...
What GPU do you have?

This discussion is not taking the direction I was anticipating, so, with all due respect, I'll bow out here.
