How to Turn Off Monitor Using a Keyboard Shortcut You can instantly turn off your monitor using a keyboard shortcut by creating a custom script launcher on your Windows desktop. While Windows includes standard hotkeys like Windows Key + L to lock your screen, this leaves the physical display powered on until your timeout period kicks in. Building a custom desktop shortcut tied to a specific key combination allows you to black out your screen immediately without putting your computer to sleep.
This article guides you through setting up a native Windows keyboard shortcut to control your display power instantly. Step 1: Create the Native Desktop Script

powershell.exe -Command “(Add-Type ‘[DllImport(“user32.dll”)]public static extern int SendMessage(int hWnd,int hMsg,int wParam,int lParam);’ -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)” Use code with caution. Click Next. Name the shortcut something clear, like Turn Off Monitor. Click Finish. Step 2: Assign Your Keyboard Hotkey
Once your desktop icon is configured, you can map any custom key combination to execute it. YouTube·MDTechVideos
