How do I change the actual full-screen resolution on desktop

As the title explains, I want to change the resolution of my full-screen node webkit launched game. Using 'set canvas size' and such methods it'll scale to the intended resolution, but the true output resolution is still my desktop resolution. Anyone have an idea how to fix this?

Most modern displays only have one true display resolution (since they have a physical pixel grid of a fixed size) and simply stretch the screen to the native resolution to achieve a sort of fake support for different resolutions. That's the same thing 'Low quality fullscreen mode' does in C2.

Ok, thanks.
