Aspect ratio is not preserved in widescreen mode.

I recently bought a 20-inch widescreen monitor. So, I launch Heroes 5... I set the resolution to 1680x1080. The image should theoretically be cropped from the top and bottom, and more should be visible horizontally. But for some reason, everything is stretched. That is, it's just a simple stretch... what should I do? It's simply unpleasant to play with these proportions. Why doesn't such a modern game have a widescreen mode???? Which patch could fix this???
