Monitor toggle

Question

To keep the backstory short i want to create a screen toggle for my laptop.

Now my first version made done using the SendMessage (SC_MONITORPOWER),
This ofcourse worked but turned the screen back on with everything even with low level hooks preventing keystrokes. (and sometimes made my screen flikker on off for a while)

My second idea was to set my VGA out to be the primary monitor (this failed due to nothing being connected) but i switched it around to TV.
Now this also had allot of downsides i could be toggled but during this time it would reset your color quality for a second messing up your taskbar icons and it also resizes to 640x480 for a second moving stuff around.

Now i know of a program called net support which is like a teacher tool to use in a class room which had the ability to turn off client monitors without any of the downsides mentioned.

So anybody have another idea?
Any ideas are welcome but the perfect thing would be something that can turn off my screen be enable by spefic keystrokes and doesn't mess with resolutions or color qualitys..

Thanks!
