I found these cool display pictures and I wonder with which software I can get such effect?

Simple - you take a digital photo without the PC screen in it, crop it accordingly and set it as wallpaper when you replace the screen.

But - it will only work from one viewing angle and one distance in that case, it is simply a photoshopped illusion.

There is no "software" that will make hardware "disappear"

Isn't making it stop working the same as making it disappear? There's lots of software that can do that.
