Are you running it full-screen? - if so, you will need to find out how to shrink the monitor so it is fitting the actual screen - usually via some buttons to adjust the X and Y on a proper monitor, no idea how to on a laptop - google the make and model and see if the manual is available online? - its how you get the instructions for your phone these days.

Or, try running it windowed - the free demo game only allows 640 or 800 wide modes though.
