Set custom resolution in-game
While in game, open the console with ~. Enter setres XXXXxYYYY (for example setres 1920x1080).

Edit ini file
Launch the game at least once then close it. Open %APPDATA%\Groove Games\IwoJima\Iwo.ini. Go to the [WinDrv.WindowsClient] section. Set FullscreenViewportX and FullscreenViewportY to the desired resolution. Notes HUD and menus remain stretched. Some menu elements become cropped.
