Windows switch main monitor hotkey

Situation

We don’t have adjustable table in our office, my solution is plug extra devices for my laptop, when I’m standing to use laptop, using two monitors, keyboard and mouse, then, when I sit working, use another two monitors and other devices.

In this way, I can switch the way me stand or sit working, but here’s one problem is that only one main monitor, when using non-main monitor, there’s some windows feature can’t see in non-main monitor.

Solution

Using nircmd.

install nircmd
write .bat to switch main monitor
- example: switch-monitor.bat
```
@echo off
cd "C:\__app\nircmd-x64"
nircmd.exe setprimarydisplay 1
```
- second line is the folder where you store micrmdc.exe
- setprimarydisplay {{ monitorNumber }}, which monitor number can be seen in display setting
run .bat file in cmd or hotkey

Finally using AutoHotkey to execute .bat file

AHK example

    ;when stand up, use monitor 1 as main monitor
    !u::
    Run C:\__app\nircmd-x64\su.bat
    return

    ;when sit down, use monitor 1 as main monitor
    !d::
    Run C:\__app\nircmd-x64\sd.bat
    return

Press alt+u / alt+d to switch main monitor
