Get information about the desktop's display mode.
Defined in <SDL3/SDL_video.h>
const SDL_DisplayMode * SDL_GetDesktopDisplayMode(SDL_DisplayID displayID);
SDL_DisplayID | displayID | the instance ID of the display to query. |
(const SDL_DisplayMode *) Returns a pointer to the desktop display mode or NULL on failure; call SDL_GetError() for more information.
There's a difference between this function and 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.
This function is available since SDL 3.1.3.
