Yes. Start menu -> My Computer, -> *C(or drive the game is on) Users\ Public\ Sony Online Entertainment\ Installed Games \PlanetSide 2 -> Open (in notepad) a file named UserOptions -> change "FullscreenWidth= " and "FullscreenHeight= " to what you want them to be -> Save and exit. Also it is ok to change anything is this file.

More help will be given if you ask around  http://forums.station.sony.com/ps2/index.php?forums/general-technical-support.29/

* This is for windows 7, if you cannot find it, right click on the planetSide2 icon on your desktop, porperties, and in the middle of the new box is a "Start in:" line that tells you where the game is located
