###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_GetDesktopDisplayMode Get information about the desktop's display mode. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_video.h) ## Syntax ```c const SDL_DisplayMode* SDL_GetDesktopDisplayMode(SDL_DisplayID displayID); ``` ## Function Parameters | | | | ----------------- | --------------------------------------- | | **displayID** | the instance ID of the display to query | ## Return Value Returns a pointer to the desktop display mode or NULL on error; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks There's a difference between this function and [SDL_GetCurrentDisplayMode](SDL_GetCurrentDisplayMode)() when SDL runs fullscreen and has changed the resolution. In that case this function will return the previous native display mode, and not the current display mode. ## Version This function is available since SDL 3.0.0. ## Code Examples ```c SDL_DisplayID display_id = SDL_GetPrimaryDisplay(); const SDL_DisplayMode *display_mode = SDL_GetDesktopDisplayMode(display_id); if (display_mode == NULL) { SDL_Log("SDL_GetDesktopDisplayMode failed: %s", SDL_GetError()); return 1; } ``` ## See Also * [SDL_GetCurrentDisplayMode](SDL_GetCurrentDisplayMode) * [SDL_GetDisplays](SDL_GetDisplays) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryVideo](CategoryVideo)
