offseting image from top

I have a game that when zoomed leave a hude black line on the bottom of the game.
What I want is to keep the 16:9 aspect ratio is there a way by matrix concat with the scale matrix to translate my game windows y position a little bit down.
What I want is to offset the top area of the screen so I can move my image wihtout changing my characters position and other components.

How can I do that, any help ?

Either use a translation matrix with SpriteBatch or take a look at the GraphicsDevice.Viewport .
