While you can always lock your computer using a WIN + L which will, in turn, turn off the display, but here is something even more useful. A keyboard shortcut to turn off the monitor display. It will not lock down the computer, but turn off the screen.
Turn monitor display off with keyboard shortcut in Windows 10
There are two ways of doing it, but both of them use the software, and they are free.
- Push Off Monitor
- Nircmd monitor off
While the first one is straight forward, the second will need a bit of work. So choose accordingly.
1] Push Off Monitor
On my laptop, there is no unique key to turn the display off, so I ended up using this portable software— Push Off Monitor. The software uses Auto Hot Key Scripts which it executes when the user uses the shortcut.
;[Settings] ;button=F1 Hotkey[Settings] button=F1
;modifier=Shift +=Shift ^=Ctrl !=Alt #=Win Hotkey to turn off the screen
After you start the program, it sits on the computer’s tray icon. If you press SHIFT + F1, it just turns the monitor display off. To resume back make mouse or press key movements and then it turns it on.
It is possible to change the hotkey. Right-click on the software icon, and click on Settings. It will open the text box with an option where you can change the button, i.e. F1 to anything else and modifier, i.e. Shift to anything else.

2] Nircmd monitor off
NirCmd is a small command-line utility that allows you to do some useful tasks without displaying any user interface. One of the features is to turn off the monitor. So if you run nircmd.exe monitor off in the Command Prompt, it will turn off the monitor.
Since we are looking for a shortcut, you need to manually create one shortcut which can be executed using a hotkey. We suggest using the Alias Manager program to do it or follow the steps below:
- Right-click on an empty place on the desktop, and choose to create a shortcut.
- Type “C:\<path>\nircmd.exe” cmdwait 2000 monitor off
- Save it on the desktop.
- Right-click on the shortcut, and click on properties.
- Switch to shortcut and create your shortcut
When you click on the shortcut, the monitor will turn off the display within 2 seconds. You can remove cmdwait 2000 if you want to turn off the monitor instantly.
