# SDL_WINDOW_FULLSCREEN Flag to request a fullscreen window, possibly with a resolution change. # Header File Defined in [SDL_video.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_video.h) ## Remarks If this window flag is included in [SDL_CreateWindow](SDL_CreateWindow)'s flags, the window will be created in fullscreen mode. SDL may change the display's resolution to accomodate this window. If you just want to cover the entire screen, and your game can deal with arbitrary resolutions, you should use `SDL_WINDOW_FULLSCREEN_DESKTOP` instead of this flag, as it will _not_ change the display's resolution. ## See Also - [SDL_WindowFlags](SDL_WindowFlags)
