Before anyone asks if this has been asked before, it has, but I haven't found a recent enough and/or satisfactory answer, so I hope the situation has changed.
I have 3 monitors (well, 2 + TV) and need to switch between them often enough that the default Windows GUI way (which involves about 10 clicks, some scrolling and some waiting) is getting on my nerves. This is on a home PC running Windows 10 Pro if relevant.
There are two setups that I need to toggle between, see image:
Case one: display 1: main, 2560x1440 display 2: disconnected display 3: 1920x1080, rotated by 90°, extending desktop
Case two: display 1: main, 1920x1080 display 2: duplicating 1 display 3: disconnected
I want to have a short script that would on execution simply toggle between the two configutation, so that I would reduce all that configuration to a single doubleclick from desktop. I expected there would be something that would allow me to select a display by its Windows-assigned ID and set its properties the way I have summed up above. Surely if you can do it via clicking in the GUI, there must be a way to do it via command line? But I found none.
There is the Microsoft tool displayswitch.exe, which is way too basic for this case.
An often recommended tool is the MultiMonitor Tool from Nirsoft. In my experience it fails at this because it seems unable to set display as duplicate, and also it seems to get confused which display is which. I tried saving both configurations while they were active and then loading them, and it botches the job, ending up with something completely different.
