The zoom is probably because you are forcing a resolution different from the native one.
It seems your monitor has HD+ as native and you are trying to use Full HD. More info here: http://en.wikipedia.org/wiki/Graphics_display_resolution
Let me know if this isn't actually the case and if I can help you further.
In the mean time I have learned that the zoom is being caused by overscanning of the connected TV.
For explanation see the link.
So the problem has been solved!
