how to display a larger resolution on a small screen

[Adrian Chen]

I've bought a graphics card which is used to professional image processing.
Hence, it could support a high resolution.Now I want it to display in
2560x1600, but my computer display could only display 1680x1050 at most. How
can I display the high resolution without changing a more advanced display?
I remember vaguely that if the resolution is beyond the display's ability,
there's one way to display only one part of the whole desktop image. And by
moving the mouse to the edge of the display, you could change the part which
is displayed. Is that I remembered right? Anyway, how can I achieve my goal
without spending more money buying another bigger display? Please help
me!!!!
Thank you very much!!!
