Maybe you can try this, but I am not sure if this is what you want:

#include 

Display* disp = XOpenDisplay(NULL);
Screen*  scrn = DefaultScreenOfDisplay(disp);
int height = scrn->height;
int width  = scrn->width;

//Create window for the ip cam video
cv::namedWindow("Front", CV_WINDOW_NORMAL);

cvSetWindowProperty( "Front", CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN );

//Position of the screen where the video is shows
cvMoveWindow("Front", 0, 0);
cvResizeWindow( "Front", width, height );

Like this you get the full screen for any screen.
