Utility to turn off laptop display

laptop: Alienware M17x

I am using win+P to switch to projector only to turn off display (it's a tricky way, since there's no projector connected). And by press and key to turn on display.

Since the fn+F1 (suspend mode) seems not only turn off display, but also turn off hard drive and something else. And I can't find a way to configure it to only turn off display.

I was wondering if anyone has a better way to turn on/off display? By using a utility? Or configure the suspend mode (how, though). Please advise, thanks.

If I do win+p / projector only, an error message appears and the screen lights back on : No projector was detected – Benjamin Crouzier – 2012-01-10T23:56:57.300

A quick google search pointed me towards this small (~85kB) utility. It works fine in Win7 for me, but it requires .net framework.

Here's a 1-KiB program that does that... no .NET Framework or anything else needed. :)

The source code is literally 3 lines:

#include <windows.h>
int main(void)
{ return SendMessage(GetShellWindow(), WM_SYSCOMMAND, SC_MONITORPOWER, 2) != 0;}

Base64 encoding of executable:
