Change screen or window resolution to 4096 x 4096

Question

I'm running a program which automatically saves images of the current view.

I need an image from that program saved with 4096 x 4096 resolution but of course my screen can't go to that resolution.

If I state inside the program that I want images with 4096 x 4096 pixels it just print screens with 1256 x 800 which is my current desktop resolution.

Is there any way of "tricking" the program into opening a 4096 x 4096 window (it would then be dragged around in my 1256 x 800 desktop) and saving those images like I want?

I already tried Infinite Screen and searched a lot on the internet but haven't found what I'm looking for.

Btw, I'm on Windows 8

Answer 1

I found out a solution.

Using GiMeSpace Desktop Extender solves the problem. Within this application I can set the size (in pixels) of each window.
