Game is rendering at incorrect aspect ratio.

[shai]

I have a monitor that is 1600x900 (16:9 aspect ratio) and when I play the game at that resolution, the game is fine, but when I play it at 1280x720 (also 16:9), the game has black boarders along the top and bottom which do not appear when I take a screenshot. The installation of the game is less than a month old, which is when I installed the OS, Windows 7 Pro. 
 
This is a screenshot I took of the game at 1280x720. The screenshot does not have the boarders, but when I was taking it, the game had them.

 

These are some pictures showing the difference in aspect ratio caused by the black bars. The first is in 1280x720 and the second is in 1600x900. You can see it best in the blocks where it tells you how big the barracks will be. In the first they are blurry and rectangular, in the second they are square and clear, as they are in the screen shot above.

You should be able to fix that in your graphic card driver settings, there should be different scaling options

 

Window mode via dune2000config would be an option too
