After looking at this article:

You seem to need to send a SendMessage call similar to:



SendMessage (Me.hWnd, WM_SYSCOMMAND, SC_MONITORPOWER, ByVal MONITOR_OFF)

Although this is the VB version. What you really need is a WinAPI call, I'm sure you can convert this bit so that you make WinAPI calls in Python. Hope this helps.

import win32gui
import win32con

if argument == "on":
  win32gui.SendMessage(win32con.HWND_BROADCAST, win32con.WM_SYSCOMMAND,
                       win32con.SC_MONITORPOWER, -1)

if argument == "off":
  win32gui.SendMessage(win32con.HWND_BROADCAST, win32con.WM_SYSCOMMAND,
                       win32con.SC_MONITORPOWER, 2)

if argument == "sleep":
  win32gui.SendMessage(win32con.HWND_BROADCAST, win32con.WM_SYSCOMMAND,
                       win32con.SC_MONITORPOWER, 1)
