Switching Display Modes

Switching display modes is performed using the following code:

   DisplayMode mode;
   boolean fullscreen;
 
   ...
   // determine your display mode in the normal manner
   ...
 
   Display.setDisplayMode(mode);
   Display.setFullscreen(fullscreen);

Make sure the context is valid upon display switching, for details see Changing Contexts

Note that the OpenGL context is maintained after the display mode change and hence there is no need to reload textures, display lists or VBOs. This reloading is only required should you call destroy() on the display.
