/r_fullscreen 0

Change your resolution in video settings to what you want.

 

modify lines below

seta r_noborder "1"   //the game will run in borderless window if "1". r_fullscreen must be "0" in order to work
seta r_fullscreen "0" //the game will run fullscreen if "1". If "0" the game runs in a window

in your config_m2.cfg found in folder "Players" in your IW4 installation directory.
