To be fair his initial request did include powering down just one... but then
he went to manually disabling one.

When I want to do what he describes I just turn the power button off on the
monitor. Seems like the simplest answer. All my windows do move to the
remaining one though (which is what one would generally want. I can have a
full screen virtual screen, though, which gets none of these windows.

My main computer has two screens, and the media computer next to me has its
own screen and is hooked to a big TV. Really the main screen is just wasted.

Simply turning power off on one monitor should not show everything on
the remaining one.

I use D:\_NirSoft\multimonitortool-x64\MultiMonitorTool.exe /TurnOff 1 2
every night in a batch and when they are turned on (manually) in the
morning no problems.

I just did the following: Open up a cmd window and issued:
D:\_NirSoft\multimonitortool-x64\MultiMonitorTool.exe /TurnOff 2
does not combine and /turnon 2 restarts OK.

I am using Win 10 Pro 64 bit with two monitors.

My mistake. I just tested it and it does not. But I was confident it used
to... so why? Aha! I used to have a bad cable and it would make the computer
at time think the other monitor was not just off but disconnected.

So in my quick test now:

* Turning monitor off: windows do not move

* Taking out cable to second monitor does. In the past the windows would not
jump back when it was re-attached, which was very bothersome with the dying
cable. That has been fixed in macOS and the windows jump back with no issue
now.

Also see below you are using Windows where I am speaking of macOS.

The color balance won't be very good.

And using an IR illuminator, that's too easy to detect.

I'm thick! I was thinking of saving power by hibernating or sleeping
the computer. This question is only about saving the power consumed by
unused monitors. I wouldn't have thought it was worth the trouble.

The computer is the recorder. They're basic cameras, so if I didn't use a computer, they would be loop recording onto an SD card and I couldn't see if they were working, or monitor them live.

Mine are USB cameras. You can buy 20m USB extenders, which can daisy chain. In fact the 20m is already two 10s hardwired - there's a repeater in the middle. You can get very long wires if you're not using a high data rate anyway, and presumably there's no limit on repeaters, although I heard once that it's 4, timing?

There are IR lights, but they're not very bright.

You don't have to put the IR where the camera is. So long as they both aim at the same thing.

It is when you have 5 screens.

Thanks for the correction -- but I just meant physically turn them off. Heck,
they can all be attached to the same power strip and can be turned off with
one switch.

How and when to do anything is up to the user and programmer.

My overnight batch is over 1000 lines long and I start it with a setup
batch which calcs a timeout wait and sets the screensaver time relative
to when it is run and 12:01 AM when the O/N batch starts. The monitors
turn off about 6 minutes later so, if I want, I can do a visual check
that it started properly.

Yes a power strip can be used manually or with a programmable outlet but
the Nirsoft command is free and does not require extra equipment.

I just move my mouse to the upper left with the control key held down and my
monitors go to sleep... or after 10 minutes or something like that.

And is likely a fine solution. Not putting it down.

There is a USB2 limit, yes.
It's five hubs on older computers,
four sequential hubs on newer computers (as Intel
added a hub to the Southbridge).
Once you've hit the limit, you'll notice
a problem with the connection. I only have
three extender cables here, so cannot test
the limiting condition.

To clock through a hub, it takes time to assemble the
packet before forwarding it. This eats into the timeout
budget.

A USB3 connector has nine pins, and five pins
for USB3. four pins for USB2. The setup of the
connection might be done with USB2, before the
device switches to USB3. As a consequence of
this, there may still be a USB2-like limit on
USB3 equipment. It's not clear whether a USB3 TypeA
would work, if the USB2 pins were snapped off.
What we do know, is the two busses are not used at
the same time. Either the five pin is running, or the
four pin is running, but not both in parallel. To
do otherwise, would require resequencing.

There are even weirder behaviors at higher rates.
For example, a USB3.0 device and a USB3.1 device
plugged into a USB3.1 hub, they're not guaranteed "fairness"
when being served. For the rich people, their labs
are filled with fun experiments to do (maybe an HDTune
result is ruined, because of the unfairness). A lot of
people, don't have sufficient kit to be running into
these cases.

But I want automation. My house lights go on and off by themselves too. I don't want to have to remember. And I don't always know if I'm leaving the desk for 5 minutes or 5 hours.

I looked it up and the limit is 7, including the computer's hub and the device, so 5. My new machine does not have nested hubs when I view by connection in the device manager, but it's an AMD. Do they not have this reduction?

I made an attempt, and one camera was fine on the 20m+10m in series (that means 3 hubs as the 20m has one in the middle of the wire), the other won't work on any extender. I suspect it uses more than 500mA and cannot be powered by USB 2. I'll have to power it seperately. Adding 5V to it isn't a problem, there's power where it will be sited. either I'll wire something up, or put a USB 3 powered hub on the end.

AFAIK USB 3.x has pathetically short cable run allowances. I read of a single metre at full speed! Fine if it's a portable drive sat on the desktop, but not if you want it at the other end of the desk.

I have a similar problem with a monitor that behaves like it's disconnected when it's just off. It goes off when the computer tells it to, but requires me to press its power button to get it back on. It's technically a TV, but they're the same thing really, just a monitor with speakers.
