可以用bat关显示器吗？求命令！！！不是关电源，是进入黑屏

VB呢

VB方法
Private Declare Function CloseScreenFun Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Const WM_SYSCOMMAND = &H112&
Private Const SC_MONITORPOWER = &HF170&
Private Sub CloseScreenA(ByVal sWitch As Boolean)
If sWitch = True Then
CloseScreenFun GetForegroundWindow, WM_SYSCOMMAND, SC_MONITORPOWER, 1&
Else
CloseScreenFun GetForegroundWindow, WM_SYSCOMMAND, SC_MONITORPOWER, -1&
End If
End Sub

nircmd -monitoroff
nircmd.exe自己找

打错了
是nircmd monitor off
