The command I use to turn off the monitor is this: powershell (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) And this to turn it on but never encloses the monitor again: powershell (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,-1)
There is a command to turn off second monitor only and to turn on again?
