Game not full screen

For some reason When I enter a game there is like a 2 in border around the whole screen. Even if I change the resolution it still stays the same. This just started happening when I defragged. The game is called Sudden attack. I tryed to change the resolution ingame but it didnt work.
Answer #1
make sure you have the latest version of direct x,
and update your graphics card drivers,
also use “cc cleaner” to get rid of unwanted files.
Answer #2
Are you playing on laptop or PC?
Answer #3
Does windows key + enter work?
Answer #4
If you have Nvidia graphics card, use the control panel to change the settings in Display -> Change flat panel scaling. If it’s not there you could be running newer drivers.
If you’re using 7 then try running in compatability mode.

look around for a game configuration file somewhere and see if you can tweak the resolution in the file manually. If you decide to go this way, make sure to backup the file first
