关闭显示器的脚本

一、用BAT脚本关闭显示器

shutdown_monitor.bat

%windir%\System32\scrnsave.scr /s

二、用BAT调PowerShell脚本关闭显示器

RunPowerShellScript.bat

@echo off

powershell -NoProfile -ExecutionPolicy Bypass -File "TurnOffMonitor.ps1"

pause

TurnOffMonitor.ps1

Add-Type '[DllImport("user32.dll")]public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Namespace b

[b.a]::SendMessage(-1, 0x0112, 0xF170, 2)

Write-Host "The monitor is now turned off." -ForegroundColor Green

效果：

显示器会黑屏，移动鼠标或键盘会恢复。
