How to impede W10 from hibernating automatically?

Mandy:
turn down the brightness before retiring to sleep.
If turned down until it is a mere glimmer, the gleam of the glowing
advertisement should not be too painful even in the gloom of night.

I turn the brightness to zero, first thing, whenever I get a monitor,
and it stays there.

Besides not wanting to see the advertisement, all the time,
my (Swiss) eyes are far more sensitive than yours.

Acer doesn't display any logo when waking up from sleep.

Nor does mine, that's standard.

15 seconds after the monitor is put to sleep
{ possibly from a RANDOM awakening },
as I'm starting to relax, "No Signal" flashes up,
annoying the crap out of me.

No monitor-review discusses this topic;
I'm the only one that cares.

Mandy replied ( to me ):
No one knows how to stop the mouse
from accidentally waking the monitor;
apparently, it can't be done.

Yes, it can and it is *easy*.
Switch off the monitor at the power button, wall socket or any
powerstrip between the two.

Then I have to deal with the flash screen when the monitor turns on.

I'm not impressed by that as an objection but, no doubt, you are.

You're not me; I'm _ very _ unusual.
As I've said, repeatedly, it's NOT a big problem.
War in the Middle East is a bigger problem.

darken the screen

I set brightness to zero and keep it there, always.

a screensaver that goes very, very dark

No such thing exists ( 100% "black" is bright gray );
I can't sleep with the back-lights on.

The solution is simple: point the monitor to the ceiling.

True, it won't be as glaringly bright on the ceiling but the
difference is probably going to be marginal when compared
to the gloom of the night.

So long as I don't have to stare at a bright object, I'm OK-ish.

Still, it's your sleep hours.
If you want them interrupted, who are we to suggest solutions ?

I don't want that, obviously.

John replied ( to me ):
Have a small, glowing lamp turn on *first* to allow your onboard
optics to adjust to seeing light. *then* hit the monitor on-switch.

No, I don't want that.

I have three or four brightness levels+areas I can turn on,
but I only turn them on for very specific reasons,
and "waking up" is not one of them.

You *never* accept any advice and any gratitude expressed
is grudging and tainted with " ... but ...".

.... John said, looking in the mirror.

Bria v5, my Win10 soft phone, responds to incoming calls.
I might be asleep, for example, with the monitor powered-off,
when someone calls me. I answer the phone ( via a mouse button )

So don't. Let it go to voicemail. Let them call back.

On Windows, my Bria soft-phone doesn't register missed calls
when it's not running; also, Bria records text messages.
I've never owned a "smart (cell) phone".

I tell everyone that I'm happy to answer calls 24/7;
I sleep odd hours, no one knows what I might be asleep or awake.

My eyes don't like the surprise.

Have you tried wearing a sleep-mask ?

I don't need that, I can just close my eyes or look away.
Also, I point my monitor towards the ceiling, away from me, in bed.
For the thousandth time, I said this was NOT a big problem.

"Oh, but I *CAN'T* do *THAT* because I need to see to ...."
Right ?

Right.

Kompressor:
Device Manager -- USB --- Find the USB port that the mouse is plugged into
Go into Power Management and UNSELECT "Allow This Device To Wake The Computer".

Nothing to de-select, not an option.

Try the Root Hub the port is on.
That is where the power management options are.

The option is grayed out.

No monitor-reviews mentioned it because
most people don't operate in pitch-black rooms, like I do;
nor do their screens look like this:

You are amazing!

What ?! why ?!

Do you also have sensitive eyes ?

Paul replied ( to me )::
My Acer monitor sets the power LED to amber, when the
RGBHV signals all go to zero DC. And the screen goes black.

Fifteen seconds later, my monitor flashes a bright-white
dialog screen that says "Attention: No Video Input".

My monitor knows the difference between computer S1 sleep
( screen goes black ) versus cable has fallen off.

When you put your monitor to sleep, you don't get
"Attention: No Video Input" fifteen seconds later ?

Maybe I should buy a new monitor;
Amazon doesn't sell a "4K OLED Monitor".

Monitor-Reviews don't mention these things;
the vast majority of people just don't care.

Kompressor replied ( to me )::

The "wake the computer" option is grayed out.

Google: USB-root-hub, "wake the computer", greyed-out

"wake the computer" is unchecked;
so I don't care if it's grayed-out or not.

I want to NOT wake the monitor -- not the computer.

Paul replied ( to me ):
Try the following. No promises.
If the monitor has a VGA input...

My 60 Hz 4K monitor uses DisplayPort v1.2 .

If all cables indicate they've fallen off,
then perhaps the monitor is in the best position to put up
the "No Signal" dialog.

Preach !

Is your monitor using VGA ?
if so, you can't duplicate my scenario.

No, but [ isn't this a ] Linux tiling window manager ?

No, the screenshot shows:

Firefox v67, Developers Edition, Windows 10 v1903, Home Edition.

Paul replied ( to me ):
Sometimes, certain combinations of those adjustment buttons
on the LCD monitor, change how it works.

My Philips bdm4037uw has only one "button": a joystick/button.

Wear a blindfold when you sleep.
You always seem to have the oddest problems.

Yes, that's my problem, no one else cares.

Different people, different problems.

And it's very much a first-world problem, not a big deal.

Paul replied ( to me ):
Check your junk pile and see what sources you
can use to "fake out" your monitor. The digital
ports seem like they need power sources to be faked out.

I am pretty sure I've got a firmware problem,
not a hardware problem. DisplayPort is funky.
VGA can't run 4K.

Jim replied ( to me ):
Maybe you should find another hobby because computers ain't the hobby for you Jeff.
Collecting pocket lint or door knobs might prove fun for you.

How's that working out for you ?

You've gotten a lot of responses from people trying to help.

Yes, people _ here would help me, if they could;
but we aren't the people who make|review monitors.

if it were such a big problem, there would be a solution,
mitgation or work around.

Right, that's precisely my point.
My problem too unique.

I hope you find a solution. I'm out of ideas.

Thank you.

I need something like an OLED 4K monitor.
Year after year, there's been little progress on that front.

Who makes the best monitors, Taiwan, Korea or ShenZhen ?

I wonder if Trump will put tariffs on them ?
