How to mirror a Computer's display onto the Iphone 4?

Instead of the usual Iphone to PC mirror, I would like to do the opposite.

Is there any way to achieve this with the USB Iphone to PC connector and software?

Yes, there's a app named I Flyair on mac to mirror a Computer's display onto the Iphone but this app doesn't work on windows

I think there's an app called iDisplay (although not pretty sure its been a while) Basically you can control the computer from your iPhone.
