Black frame insertion into monitor help needed

[intikhab]

I have read around the internet but google searching can't seem to give the answer for what I am looking for. What I want is:
How can I insert black frames into my or any monitor using software for everything rendered on it and to test things using this approach?
I can write programs in c++, c# and few other languages but mostly basic to advance level little bit expert level. So any help is appreciated in this regard. the purpose is to reduce or eliminate the blur using above method and study limitations on it using software and different hz.
PS: I hope someone helps me out.

I would start by making a black image in an image editing program. From there you can copy it into a series of files. then convert this into an animated GIF. You can adjust the timing between images when you make the animated GIF.

but I need actual frame insertion of black into gpu output to test it for performance and draw backs of real time usage. The way you explained can be used for video testing though, will try that in matlab if it allows to merge multiple video merge.
