The GUI way to disconnect the display is to:
Open Settings -> System -> Display.
Select the monitor that you want to stop displaying to.
Under Multiple Displays dropdown select Disconnect this display.
Select Keep changes when prompted.
Open Settings -> System -> Display.
Select the monitor that you want to reconnect.
According to the screenshots you provided, I noticed that the People view is displayed in the "Calendar view" screenshot. I conducted both the two tests in my outlook 365 client (version below), but didn't reproduce your issue.

"E-Mail" view to ...
That's simply a question of geometry and resolution. Example:
For the sake of simplicity the resolution of both monitors is 100x300. Viewing the image as it is the green line appears clearly shorter than the purple one, but in pixel count they are both exactly 100px long.
In this case the difference is caused by the screen geometry. Difference in resolution ...
On Windows 10, go to
Advanced Display Settings → Remove display from desktop
section... there's an option to
Prevent Windows from using this display.
This display will be available exclusively for special-purpose apps that require it.
Try that and see if it works for you.
Intel HD Graphics 4600
can in theory support three monitors
However, this requires more graphical ports than are available in
Also, this being a notebook, it's not possible to add in
a new graphic card that supports DisplayPort.
I think you will need to settle for two monitors, connected to your
You could find the number of monitors and used lanes by using the free
Under the Advanced tab, you will find the monitors and the number of lanes
taken by each one. From this data you may find the number of
DisplayPort signals taken off the bus:
You could use Device Manager to disable the built-in display adapter just before you call this software. This way you will only have one display when running
In the worst case that your computer crashes with the adapter still disabled,
it will be automatically re-enabled on reboot. (Although it's safer
to re-enable it before shutting down the ...
Adding to this thread for future folks who land here from search. I found this reddit post which lists some options. Notably:
Fresco - free on Mac app store. I tried it and it worked well.
Superpaper - Open source and cross-platform (though it says it hasn't been tested on Mac, I didn't try).
The voltage is dipping when your air conditioner kicks in. This will happen if your PC and/or AC is a long distance from your breaker panel AND they are on the same circuit. On start up, the AC is drawing more current which means the voltage drop to the wire or I2R losses goes up decreasing voltage at load and hence the monitor shuts down.
I've solved the question.
The Monitor Section regarding "Mac" was ignored because the association in Device section is
Option "*Monitor*-outputname" "MonitorIdentification"
Option "Outputname" "MonitorIdentification"
HOW I SOLVED THIS: Your 4K monitor has a ratio of 2160/3840 = 0.5625
Adjust the other monitors to the same ratio (0.5625) by choosing one of the available resolutions.
Then, make sure you have the same "Scale and Layout" magnification in all three monitors (if you have 150% in your 4K monitor, make it 150% on the other monitors too).
On windows 10, I needed to connect 2 monitors as well, and the answer is: you need to get to the boot BIOS menu and go to the display and graphics settings for your motherboard and enable onboard graphics.
There are a few videos on youtube that will let you know how to do that just type "using GPU and CPU for displays" in search engine. Were I was ...
Multiple Monitors program does what you want, although it's not free. It has a free trial to check it out.
I tested it with 2 monitors. Going right from right one does send you to the left one like in PacMan, but going up or down only sends you in the same monitor, not the other one (which would me a bit disorienting in my opinion).
The rendering of the windows is done on the X server (Windows). The X client, does not do anything with video processing. In fact, I have even run remote X applications on servers without any graphics adapter at all (Sun SPARC hosts), which ran fine.
Of course if you run any Linux applications that require CUDA or OpenCL capabilities, those would require a ...
Open the Device Manager (devmgmt.msc) and switch it to View→Devices by connection mode.
Expand the tree (starting with "ACPI-compliant PC") until you find your graphics cards, and although it doesn't show ports, the actually connected displays should show up under the cards.
(In laptops, however, I think HDMI is usually wired to the internal GPU, ...
Yes, this is possible but requires software. Depending on how fancy you want it, it will either be not seamless or may cost money.
