Why wont the image take up the entire screen on my 21 inch monitor?

Q: I recently sent my 21 inch monitor to be repaired and in its place they gave me a 17 inch monitor…now that I have mine back, the size of the screen is stuck to the 17 inch screen. I have already tried ajusting the resolution and screen size but all that does is make the icons larger or streches them out… if i ajust it to the resolution I want and the icons are the size I want, there is about 7cm black space on each side that I cant use! How can I fix it so the whole monitor space is being used without distorting the icons and their size? I have Windows 7…
