I uninstalled match explorer because i couldnt seem to get full screen without my start menu thing in the bottom ( dont know what that is in english ).
So i uninstalled explorer but i still have the same problem that my game isnt completly full screen as in i still see edges.

Had the same issue.. EASY to fix. Just delete the COMMONS files in your main FIFA directory and your all set.

delete COMMON.INI in your fifa main dir
